When I dropped my son off at college, we found that he was
assigned to the fourth floor of a dormitory. As I trudged
through the parking lot to retrieve yet another load to
carry up the four flights of stairs, two young women caught
my attention from a dorm window. "Hey, Mom!" one called
down. "Yo, Mom!"

I was too tired to respond, so I just ignored them until I
heard the second girl ask the first, "How do you know that
woman is somebody's mom?"

The first girl replied, "Who else would do that?"
