I started working in the family garden center when I was about 9, running the cash register. It was old school,. Didn't show digits, just number places with dots, and you had to pull the handle to make it print each transaction on the tape. Looked like something you'd see an accountant use in an old movie. You know, the guy that was always wearing a visor? Of course in those days, cash registers didn't compute the change for you, you had to figure it out for yourself. I was forced into getting good at "maff" at an early age. So the price I paid was child labor and no summers off.
As for the age I kissed a girl? Not sure on the "peck on the cheek" or bumping lips, but the first heavy duty french kiss session was at 14, and no, I cannot make balloon animals.
