Yes, truly a bit*h.

Have you ever wondered that karma is really a bit*h?
That it gets back to you sooner or later?

Like when you laugh at someone because he/she trips down, the next day, you fall down twice harder.

Or when you behave badly during your youth, that your children will somehow follow your behaviour in the future?

Or when you hurt a feeling, that yours will be hurt too?

I just hate it when it gets back to me. Well, a lesson that I never should do bad things to others. 
But you see, it is hard when you do it unintentionally and without you even realising it. By then,please tell me how to prevent it from happening. PLEASEPLEASE  PLEAAAAAAAAASSSSSSSEEEEEEEEEE!
