Basically my (22M) life. I'm shy when it comes to big gatherings or when I'm with girls I like, so I ignore people because of that shyness and I'm automatically labelled as the rude guy who's full of himself even though it's not like that at all. When I'm comfortable I can have conversations and be a bit outgoing. Also my resting face doesn't help the arrogance accusations.
So, how can I tell people that I don't hate their guts and that I'm just shy without saying it directly ?
