No one mentioned double dipping....I will not eat something that someone else has infected with their saliva.

When I was a little girl; the one time that I recall my Swedish mother being physical with me was when she slapped the spoon she was using to stir the pot Outta my mouth!!!!!
"Do you know that the dirtiest part of your body is your mouth?" She yelled.
"And I'd be putting that spoon-with your germs back into the pot so everyone can have get some of your germs from MY MEAL!!!!!"

I have very strong feelings about this one. She taught me well.---ick, ick ick
