My brother was four years old, and I was a year younger at the age of three.
Randy was in the middle of our living room floor playing with his toy car carrier truck when I came through, and accidentally stepped on it. It upset him, and so he begin chasing me through the house, the both of us ending up at the back door. The next thing I knew, he was pushing me through the glass. Mom came hurrying in to see what had happened. There I was crying and screaming, with glass all around me, and my arm full of blood.
Mom was on the phone the very next minute telling my grandpa to hurry and get over to the house right away. Randy knew that he was in a lot of trouble, and did not want to be found by grandpa, so he ran and hid under his bed. Our grandparents lived very close, so grandpa was there very soon. Randy of course got in a lot of trouble, and I had to be taken to the doctor's to get a lot of stiches all because of a little toy truck!
