What is the right time to go crazy??

I was 5 years old and my little brother was 2 years old. We wanted the same toy to play with. My mom said give the toy to him as he is soooooo little. Your little brother..I felt bad but alas! I gave the toy to my brother. So there goes....Everytime I wanted something i was asked to give it to my brother as he is my younger brother. I am not complaining, I love my brother. The whole point of letting you guys know this side of my life is to let you know where the trend began for me to be more sensible.

So as I was saying, there was always a time when I wanted to do something different or wanted to be somewhere else but I could not. Cause duty comes first. I have this terrible tendency to choose what is good for everyone instead of choosing what I want.

Let me enlighten you with an example of an episode that happened with me recently (I know you did not ask for it, still..). It was my birthday and all I wanted to do was to sit at home, eat nice Chinese junk food and peacefully watch some nice movie on TV. But what happened was, I had a lot of guests (mind you, these guests did not even know that it was my bday, they just showed up on my doorstep randomly on that day) and I "cooked" all the different dishes that "they" wanted to eat. And ended up doing what all the rest of my family members wanted except what I wanted. 

There are times when I feel "Chuck it man, why should I be the one to do as per what others want. why? why?" and then I answer myself, "Come on, you know if you do this now you will get all the others mad at you plus you will disrupt the entire schedule for them. So be a good girl and just forget it. Continue with what ever is going on. phewwwwwwww."

In short, everybody in my family goes crazy whenever they want. They never make much adjustment. And me being the guilt queen always end up adjusting. So anyway I realized if I continue this way I don't know "What is the right time to go crazy???"
