Cracking Jokes with Friends

When I was in high school, I always enjoyed cracking jokes with my friends. We would come up with funny ways to make each other laugh and it was a great way to relieve stress and have fun together. I remember one time we were all feeling down because of a test that we had just taken, but I cracked a joke about how we were all going to fail it and it made everyone laugh and feel better about themselves. I think that"s what makes a good friend - someone who can make you laugh when you"re feeling down and who can appreciate your humor when you crack a joke at their expense.
