Why do guys initially ignore me, am I missing something?

I'm not talking in here of course people here are really nice :)

but in real life, guys usually ignore me, I have lots of guys friends but usually when they first meet me they completely ignore me, like when there are a big group they talk to everybody expect me like I'm not even there I don't show it but it kind of hurt it makes me feel left out.

The other day I went to a park with my best friend (girl) and then there was a guy that she knew and he talked to her the whole time and when he left he only said by to her, I though it was very rude.

Anyways what am I missing
