Especially if you know what physiological symptoms & behavior to look for.Go to the bar or cruise skidrow. If you can't find coke you're hopeless.
The ones who complain about loneliness are very much being cunts. If you're friendless because you're introverted but you're at peace with that that's one thing. I'm referring to people who go "BLOOBLOOBLOO NOBODY LIKES ME BECAUSE I'M WEIRD" as if the world isn't full of weirdos with friends. It's not hard for anyone who's not completely self absorbed or physically incapable of going outside.Some people are just boring, introverted, odd or shy or whatever; I guess that's a thing wrong, but it's not like everyone like that is being a cunt.
