Finally, I come back.
I can feel every body, more or less, in kind of depressed mood.
I'm not sure what recipe of those.
I think, at least, currently the result is safe.
I didn't do any thing need to be regretted.
Let any stupid thinking gone.
Let everything calm down.
Let everything back to normal.
Nothing be destroyed.
I'm happy!
I know every thing that why I feel like this.
But the most difficult part is the transition time.
If I cherish this friendship enough, I will not do anything to destroy it.
