Cool Drool?

Okay, say you're sitting with your one-year-old and they want you drink from their cup with their straw. You do it, right?

And then what if the next day, your grandpa wants to share his drink with you and he's drinking from a straw, too. Do you drink it?

No? Why is that?

Is it because Grandpa has yucky germs? Or do you think Grandpa has more germs than your child, even though you're all from the same gene pool?

After all, it's the same strain of DNA in the drool, right? Baby or Gramps, same dif, don't you think?
