I frequently think of good jokes when I want people to like me but they tell me my jokes aren't funny
What's the reaction after you tell them?
I'm just laughing when I tell my joke and they don't understand it
It's okay if some people don't find you funny. You should keep telling your jokes and eventually you will find someone with your sense of humor. It wouldn't hurt to adjust your jokes based on your audience though.
I'm going to call a friend and ask them what they like to hear.
It's good to get input from friends on your jokes. Even if they don't like them, they might give you tips on how they can be more relevant to them.
