Mmmm, according to you, how to talk to someone that we just know? I think, we can use to talk about something in general. Likes, how's the weather? Or talk about something that he/she like. In order to do this, you can use Direct Speech and Indirect Speech. And let's learn about that.
Direct Speech / Quoted Speech 
Saying
exactly what someone has said is called direct speech (sometimes called quoted
speech)
Here
what a person says appears within quotation marks ("...") and should
be word for word.
For example:
She
said, "Today's lesson is on presentations."
or
"Today's
lesson is on presentations," she said.
Indirect
Speech / Reported Speech
Indirect speech (sometimes called
reported speech), doesn't use quotation marks to enclose what the person said
and it doesn't have to be word for word.
When reporting speech the tense
usually changes. This is because when we use reported speech, we are usually
talking about a time in the past (because obviously the person who spoke
originally spoke in the past). The verbs therefore usually have to be in the
past too.
For example:
 
  | 
Direct
  speech | 
Indirect
  speech | 
  | 
"I'm going to the
  cinema", he said. | 
He said he was going to
  the cinema. | 
 
Tense change
As
a rule when you report something someone has said you go back a tense: (the
tense on the left changes to the tense on the right):

Indirect speech | 
  | 
"I might go to
  the cinema", he said. |

You
can use the present tense in reported speech if you want to say that something
is still true i.e. my name has always been and will always be Lynne so:-
 
  | 
Direct speech | 
Indirect speech | 
  | 
"My name is
  Lynne", she said. | 
She said her name was
  Lynne. 
or 
She said her name is
  Lynne. | 
 
You
can also use the present tense if you are talking about a future event.
 
  | 
Direct speech (exact quote) | 
Indirect speech (not exact) | 
  | 
"Next week's
  lesson is on reported speech ", she said. | 
She said next week's
  lesson is on reported speech. | 
 
Time change
If
the reported sentence contains an expression of time, you must change it to fit
in with the time of reporting.
For
example we need to change words like here and yesterday if
they have different meanings at the time and place of reporting.
 
  | 
Today | 
+ 24 hours - Indirect speech | 
  | 
"Today's lesson
  is on presentations." | 
She said yesterday's
  lesson was on presentations. | 
 
 
  | 
Expressions of time if reported on a different day | 
  | 
this (evening) | 
› | 
that (evening) | 
  | 
today | 
› | 
yesterday ... | 
  | 
these (days) | 
› | 
those (days) | 
  | 
now | 
› | 
then | 
  | 
(a week) ago | 
› | 
(a week) before | 
  | 
last weekend | 
› | 
the weekend before
  last / the previous weekend | 
  | 
here | 
› | 
there | 
  | 
next (week) | 
› | 
the following (week) | 
  | 
tomorrow | 
› | 
the next/following day | 
 
In
addition if you report something that someone said in a different place to
where you heard it you must change the place (here) to the place (there).
For example:
 
  | 
At work | 
At home | 
  | 
"How long have
  you worked here?" | 
She asked me how long
  I'd worked there. | 
 
Pronoun change
In
reported speech, the pronoun often changes.
For example:
 
  | 
Me | 
You | 
  | 
"I teach
  English online." | 
She said she teaches English online. | 
 
Reporting Verbs
Said, told and asked are the most common verbs used in
indirect speech.
We
use asked to report questions:-
For example: I asked Lynne what time the lesson
started.
We
use told with an object.
For example: Lynne told me she felt tired.
*Note - Here me is the object.
We
usually use said without an object.
For example: Lynne said she was going to teach
online.
If
said is used with an object we must include to ;
For example: Lynne said to me that
she'd never been to China.
*Note -
We usually use told.
For example: Lynne told me that she'd never been
to China.
There
are many other verbs we can use apart from said, told and asked.
These
include:-
 
  | 
accused, admitted, advised, alleged, agreed, apologised, begged,
  boasted, complained, denied, explained, implied, invited, offered, ordered,
  promised, replied, suggested and thought. | 
 
Using
them properly can make what you say much more interesting and informative.
For example:
He asked me to come to the party:-
 
  | 
He invited me to the
  party. | 
  | 
He begged me to come
  to the party. | 
  | 
He ordered me to come
  to the party. | 
  | 
He advised me to come
  to the party. | 
  | 
He suggested I should
  come to the party. | 
 
Use
of 'That' in reported speech
In reported speech, the word that is often used.
For example: He told me that he
lived in Greenwich.
However, that is optional.
For example: He told me he
lived in Greenwich.
*Note - That is never used in questions, instead we often use if.
For example: He asked me if I
would come to the party.
