I know but you can write for other people.

I have a tip, before you have a conversation you can create a story with two character, for example:

A: Hi, how are you?
B: Hi, I'm fine.
A: Nice weather today, isn't it?
B: Yes, it's.
A: So, I don't see you last weekend. Tell me what did you do?
B: Oh, I had unbelievable weekend.. I was a big party on Friday and guess what! I met a amazing girl... bla bla ...

Because the majority initial conversation it's about description for something in present or past.

And sorry my English, I'm improving too.
