Are you laughing because it is funny or belittling someone...?

Don't laugh or jest in a way that you belittle someone esp. someone of higher authority. 

Be constructive and do it for others' good but not laughing down others as if  they are a clown and dump and stupid. It is easy to feel tickled (to appear as if it's a light-hearted affair) and seen to be one up to be able to laugh at others' mistakes, but that action can be sensitive to others esp if he/she holds a high authority or position.
