A cool person to me is being real. Being themselves and not caring how other people view what they say or do. When I say you're cool, that's what I mean. Today too many people are concerned how others view them. Posting pictures on social media sites of themselves on vacation or where they are eating dinner that particular evening. Fuck that. Do things for yourself and for YOU to enjoy it, not to show everyone else what you're doing.
I enjoy spending time with my friends because they're cool people.
I wouldn't go out with a girl/guy that isn't cool.
