Well, I asked a question about several weeks ago. I accepted the answer, but I didn't upvote it, not because the accepted answer is not good, but I have already accepted it.
I'm not stingy to give him/her an upvote,but I am just curious whether it is an unspoken rule that I should give him/her an upvote if I accepted his/her answer?
Ps. I'm not angry with anybody. :-)
