An Acquaintance is someone who you see around and are definitely involved with, but you don't
like them enough to call them a friend. Hugging them would be extremely
awkward, and if you plan on hanging out with them bringing one of your actual
friends with you is a must so things don't get boring, awkward, or silent.
Person 1: You know each other? How long have you been
friends for?
Person 2: Oh no
dude we're just acquaintances.
Person 1: You aren't
friends?
Person 2: Nah man we don't hang out like that.
