Anything friendly with a pulse. Standards low enough yet?
I'm trying to think of a way to say this without sounding snotty, because I truly want to help you, but if your outlook on life and people in general in person is anything like the one you portray on this forum, you're probably going to have a hard time finding finding anything friendly.
I don't know how you dress, or how you groom yourself, but keeping up appearances is a big thing. This doesn't mean having a 6 pack or having a jaw so square and sharp you could cut a G-string with it, but it does mean looking like you've given at least half a damn about the way you look. That was something that took me a long ass time to wrap my head around, because I was always like "I don't want a girl if she's only interested in my looks, blah blah blah super deep, stupid, stubborn reasoning". Well turns out that when you look like you don't give a damn how you look, other people will figure you don't give a damn about much of anything at all, and apathy is deathly unattractive.
Also, smile more. If some one looks at you, smile at them, it instantly sets the tone that you're friendly and approachable.
