An Irony of Parenthood:
When your first child is born, you carry around a hand-santizer. At all times.
You actually go so far as to place it in the carseat next to the newborn reminding on-lookers of their incriminating germs and your full support of their improved hygiene practices before touching your child.
Fast forward 5 years.
Gone is hand-santizer. Replaced is the plea:
"If the dog licks you in the face, just please make sure to keep your mouth closed."
