I met this girl through a friend online.
I'm interested in her, and I can see that she is interested in me.
The problem is that I have trouble with thinking what to talk about.
Can anyone give me some advice on what to talk about, and how to bring it up? etc

~Thanks in advance.

We cant tell you what to talk about, just make general small talk, ask questions about her, and dont let there be a silence, as they are awkward.

Failing that, rape.

Ask a lot of questions, even if you don't care what the answer is. Pretend to listen to her talk. Girls love talking about themselves and being heard.

Dont pretend to be interested...

You sure you wanna be with someone with whom you have to pretend to be interested in what she says?

She must be hot.

Pics or it didn't happen!

Just be different from the last 5 guys she talked to.

Be a bit random.

Be funny.

Be rude.

Be sexual.

Be arrogant.

But mainly, just be yourself. Thats what she'll see after a while anyway.

Yeah, just be yourself. Bullshittery is never good in the long run, and can be bad in the short run if she has a decent sense of smell.

Get straight to business and ask her if she wants to toss your salad.
