Debbie,
I too had a chuckle, I work in family practice and when I come home from work the first thing I do is change clothes and wash up. I try to protect my family from my daily germs and I dont even have babies human or canine.
But I cant tell you how many times I get coughed or sneezed on during the day. No one covers their mouth anymore.
ETA: Ok not everyone coughs without manners, but some.....
