Yeah, I think you just have to be a bit better judge of how someone else will react to you.

Sometimes people will be much more shy in the day, remember in the night they're round there friends having fun and probably a bit tipsy. If you approach in the day they might be a little unnerved an worried about how to respond therefore just appear rude and run away.

May well not be what you did, may well just be there shiness. As above though don't be disheartened. I just think it's going to take that little bit more effort and attempts to ge the hang on judging the situation.
