There may come a time in your life when you "
hang out" with certain people. You can have
fun with them (but not always), you can have a
conversation (but not a meaningful one) and they will back you up when you are in
trouble (but only if it is also in their interest).
These people are not your friends.
You may be in need of them, since you might not have any other people to converse with, and wouldn't know what to do on Friday and Saturday evenings if you didn't have them.
But never believe they would ever really help you out of a pinch or lend you a helpful ear, a strong shoulder.
These are not your friends. Get some real ones. Now.
