Changing in Mood

Last night my heart was heavy, still a Taiwaner girl complained her parents a lot for a month to me. But she never thought that she is the biggest problem. About this Ms.Complain, she told me that she hates her father forever, then I think of my father. I told her my father's behavior to let her know that her father is not the worst, of course my father is also not bad, just he is irresponsible. I dislike that Ms. Complain always complain everythings but never made a contribution. Moreover, her speech tone as if I have to answer her questions and the questions always repeat and repeat. She made me feel worse after I got a bad news.
Something like that always happen in the life, I always know how to turn a bad mood into a good one. Yet, last night I got a bad news that my aunty's husband passed away because of flooding in typhoon. And then she seemed to be in a trance until the neighbors found and called the police officers. She is my mom's second elder sister, and she has no children. If no one wants to take care of her, then she would send to the nursing home. So now she is in my home.
I was not in mood to chat on the internet. Originally I thought this time I need a week to change mood. But I only spent a day.
The morning time I finally got the receipt of the foundation which I donated. And I did the 3 hours volunteer job. During this perioud, my emotion had moderated little by little.
