Well I guess under certain circumstances you have too, but people who go out to attend social gatherings while they have a cold or a touch of the flu need a good swift kick in the ass. I go to a house warming this weekend and like 4 people there are sneezing, coughing, hacking, blowing their nose etc. Today I wake up and I feel the beginning of something. Back is a little stiff, sore throat, feeling tired.
I asked all the sick people there if they liked being sick so much they felt the need to share their germs with the rest of us. No reply just funny looks.
