People who want to hang out with you for the sake of hanging out. People who enjoy being in your presence and like you for who you are, rather than for what you can give them.

Someone used to invite me to "hang out" with her and whenever I get there, she would ask me for favors or seek my help.

I can only remember one time that we actually hung out and really just hung out (she actually asked to hang out longer that day but I said "gotta go" and left. Had I stayed longer, she probably would have asked for favors).
