We are usually unhappy because we are missing something. The moment we learn that missing element, we start getting happy.

Quite often it happens that people crack jokes on us and we feel insulted and get quite angry and try our level best to retaliate. But does that stop them from their constantly ridiculing ?
I had a classmate in my school days who was quite fat (he was obese). Everyone in the class used to tease him by calling him fat and several other nicknames and every time that guy replied by saying, "does your dad feed me?". This was his fixed reply to every attempt made by the people on his obesity. The sad part is, he had no friends! Every time someone joked with him, he reacted in this way and this attitude of his wasn't very much accepted by the classmates. He was disliked. This attitude of sulking cost him very much in his childhood.

What's the issue?

Whenever we are in the face of mockery or ridicule, we usually have 2 ways to respond.
1. We get irritated and agitated and we want it to end that very moment and for that we try to put the other person down.
2. We go with the flow and enjoy the humour. We laugh with them and sometimes even start cracking jokes on ourselves.

We work all the time to create an image. We want to be likeable and respected and when someone tries to attack us, we try to defend it with full force. But where is this taking us ? Lets consider the 2 cases talked about earlier.

Case 1 :
We want others to like us.
For that we try to create a good image of ourselves.
People attack that image, for fun.
We become defensive and start sulking.
Now people dislike us for that attitude.

Case 2:
We want others to like us.
For that we try to create a good image of ourselves.
People attack that image, for fun.
We let them attack it and have fun with them.
Now people start liking you.

Do you get the irony? We work hard so that people like us but by choosing the first response, we make them dislike us.

What do we conclude?

The person who let others make fun of him is more likeable than the person trying to protect his likeable image, fiercely.
I am not saying that start mocking people around for their traits BUT if the situation arises in front of you, face it bravely and in a fun way because in that way, you won't get upset and if you don't get upset you'll become happy. Also, the other person will stop teasing you or mocking you, eventually so it's a win win situation.
So just stay happy!
