Last week we were invited to a birthday party for my husband. Unbeknownst to us, the hostess had a cold. She only told us much later, and said, "but its okay, I took cold meds."
What she and so many people do NOT realize about such things is that they relieve your symptoms and "let you get back to work" is that while you're not coughing and sneezing, you are still contagious. So in a way the cold that would have kept you home and safely away from the rest of us is now out there in the workforce, or at the teacher's desk, or breathing on your 85 year old granny.
Her family is now covered with colds, and has no idea how they got them. My husband came down with his yesterday. Sigh.
