Can you laugh at yourself?

To be able to laugh at yourself is a gift. It's a unique ability to to be able to put the the other person with  whom you are, at ease.It's a lethal combination of modesty and humorous self-confidence which makes you extremely likeable as an individual.It lets you show vulnerability without weakness and encourages others to empathize with you. Then why is it that some of us are so scared of practicing this? What is it that makes us so straitlaced and boringly proper? Maybe it's because we are inwardly very insecure and try too hard to fit in with the crowd that we take every comment as outright criticism or compliment. I think we need to go easy on ourselves and rediscover the ability to have at our expense rather shredding others to pieces.
