Do you believe in it? I do and I saw it happened.
So, I been cursing other, who been bad to me, for having bad return. But I wouldn't go and curse other just like that. As long that person never step on my "tail" or "stab" my back, I just let it be. Sometime really sick of those "xiao ren", maybe it's fated for us to get this kind of people and let them be punished in the end.
