Meaning of friendship
What friendship means to me!
They are referring to that they get along they are making each other laugh and they show that they are happy to be with you. If they weren't happy to be with you or didn't want to be your friend they wouldn't be laughing or smiling at the things you are saying.
They want you to know what your doing wrong but they don't want to go talk behind your back and you find out from other people that they said that. They want to tell other people good things about you so they think your a better person. When they tell you bad things to your face they just want to tell everyone else what you feel about them, your friend should be happy that you tell them what they really think of you, or if something is going wrong that day they go to their face not behind their backs.
