Arent they so much contagious. Especially when it is without any reason, atleast apparently. Now I, being a sensible adult, find it really unfair to be bad to someone if im having any personal peroblem. But well it happens, sometimes we become unreasonably unfair to others. Frown, taunt, or atleast stop talking without any apparent reason. What would you call this? such an attitude is really upsetting, for me atleast. How do you people react, if confronted with such an attitude, anytime. Please share.
