I'm jumping on PT's stories-about-myself bandwagon:
My mother's favorite story about me:
I'm not sure exactly how old I was, but I was old enough to talk right and I couldn't pronounce the letter "L." My parents took me to this speech therapist, to that speech therapist, but nothing was working. Then, one day when I was sitting in the back seat of my mom's car, I started singing a song from Sesame Street: "La-la-la lightbulb. La-la-la lollypop." And then shouting, tune be damned: "La-la-la lightbulb! La-la-la lollypop!"
My grandmother's favorite story about me:
Again, no idea the age, but young enough for this to be cute. We were at some fancy restaurant, and I ordered French Fries. They turned out to be big, thick, wedges, or possibly steak fries, while I was used to the skinny, crispy, fast-food variety. I took one bite and said, "I don't like these french fries - they got potatoes in 'em!"
