A friendly person smiles and shakes your hand when introduced to you, and continues being genuinely warm to you thereafter (doesn't ignore you, doesn't seem stand-offish). A non friendly person is basically the opposite of that. Even ultra-reserved people who aren't necessarily rude come off as being non friendly to me.
A friendly person wears a smile .. non-friendly - growls .. :)
some one that can chat and laugh easily!
Someone who takes me as they find me and isn't judgmental.
