A couple of years ago, when I was picking up my daughter from the bus stop, the bus monitor (a nice, but slightly crazy lady in her 60's) told my daughter to stand aside and said "Mr. Dancona, we need to talk".
I was worried for a moment, until she told me that my daughter had kissed some boy on the ride home and that I was to make it clear to her that that type of behavior would not be permitted.
I thanked the bus lady, and then as the bus drove away I burst out laughing. I gave my daughter a hug, and told her it was silly... but that she should still listen to the bus lady.
My daughter and I still joke about it, I will tell her "No kissing on the bus!".
