Big Golem – personally, I would be a bit cautious about giving any kind of gift if either of you is not feeling emotionally connected to the other. I remember feeling very uncomfortable when someone I went out with who really liked me (and whom I didn’t like) gave me something.
The “gift” itself I wouldn’t have minded (it was Divrei Torah – something he had gotten ahold of that he knew I would want and he had photocopied for me), but the fact that he wrote a note on it made me very nervous. He didn’t even write anything so terrible, but the fact that he wrote a note made me nervous.
Chocolate is fine – I never minded when guys I went out with gave me chocolate. But I would be cautious about notes. That is just my opinion though – I don’t know how other girls feel.
I do vaguely remember once when I set someone up and the girl wrote notes for the boy (it was her type -she used to that in general- I’d gotten several notes from her on different occasions), and I think I remember his sister telling me that it made him nervous. And they had been going out for a while at that time. So it could be it’s not just me.
I would also be careful about giving flowers too soon (I remember there was once a thread about that). My friend’s chosson gave her flowers a while before he was her chosson and she wasn’t ready for something like that, and it made her nervous.
But then again, these things all depend on the people and the situation. I would try to stick with something as neutral as possible though – like chocolate. But that’s just my opinion.
