catching a Cold from a Co-Worker

of all the things that a co-Worker could pass along to you, the almighty yearly Cold. all the Coughing, Sneezing, tissue, cough drops, Cough Medicine,and just feeling you are tired. hearing a a Co-Worker describe the same things that you got gets a well if that is the case then keep your Behind at Home. I mean just getting over fall&early Winter&then getting hit with a fresh cold daily&weekly isn't the kind of gift you want to be presented with. of course a Co-Worker could make some Food&Upset your tummy&to me messing with my tummy is even more serious than catching a Cold,though they aren't that far off.sleepless nights&alot of tossing&turning all through the night.Don't worry I don't believe in returning the favor.
