I dont have any friends.
In my mind a friend is someone within my age range that I can talk to/hangout with. Someone who I have something in common with.
I can separate friends by online, real life etc
I cant meet someone and call them a friend after one day. Kids do that lol My little sister makes a new friend almost everyday just by saying one thing to them.
*They dont have to be within my age range but its easier that way.
