People who seem to be in a bad mood for watching are never unusual.
"In a train" "at a restaurant" "at a convenience store" ... I will encounter in every situation of my life. Of course, just being in a bad mood seems to be bad, maybe you are in a good mood.
Realize the importance of the mood! Tweets about such "mood" are gaining attention.
