Why does my best friend do this to me?

My best friend still think I like my ex but I don't he is just funny. Me and my ex get in arguements and then like 15 min. later I laugh at him but that is because its funny I am not going to hold in my laugh if I think something is funny. but when I tell my best friend about the arguements we have she just kinda doesn't listen to me but then after I am done she says but how do u laugh at him 15 min. later. I says he is funny. my best friend doesn't laugh at stuff that is funny sometimes so she doesnt' laugh at what I laugh at. so who do u think is write me or my bestie

in this situation, if I were you, I would just let it go. your friend is probably just jealous that you can take things as a joke rather than really getting into them. just try not to worry too much about it.

Friendship doesn't mean both of you have to see everything the same way. It means you enjoy each others company. You can laugh at what you want and so can she. It's not a question of who's right, it's a question of who's funny to each of you. One of the best ways to maintain a friendship is to accept each other as you are. Trying to make someone different than their natural self has destroyed many good friendships. You and your "bestie" should have a good laugh about this and move on.
