<human>: Could you distill the essence of the text into 1-3 sentences?

So I went on a date with a girl, Gina, yesterday and I really felt like we hit it off. We had a great time and there was real chemistry. So I've had some dates here and there but this one feels like it could go somewhere.

Anyways, I tried to see if she wanted to hang out tonight after work but she was busy with a friend. She's still interested in doing a date so I'm unconcerned about that aspect. I thought that since I like her, I would mail her a letter with a few jokes, maybe say something like "I was sitting here thinking to myself how sad it is that we are slowly losing such a romantic form of correspondence" with a couple jokes. I spoke to my friend and he's *heavily* against this plan and I'm starting to second guess myself.

Also, I know her address since I picked her up for the date. My friend is saying this makes it a very bad idea.

My friend is suggesting I wait until at least after the second date before I do this. I feel the possible upsides outweigh the downsides. Am I wrong?
<bot>: I went on a first date with a girl yesterday. I want to mail her a letter as a friendly/romantic gesture. Is that creepy/weird?
