Sickening

When did it become okay to take your sick kid over to someone else's home? I'm all about parent taking date nights, but not when there is a sick kid involved. Don't call and ask to bring your kids over so you can go see a movie w/out disclosing to everyone in the house that the kid is on the end of a cold. Now I have a cold, and I'm rather displeased about it. Clearly.
