At 5 and 6, I was 6 and he was 5, I got one of those metal dollhouses for my birthday and, to my dismay, he got a big fat metal airplane......on MY birthday!
Somewhere near that age we were going to marry. each other.
When I was 10 I had to take the "little ones" trick or treating, he got to go as far as he wanted and would come home with grocery sacks full of candy, he was a boy. Once we made a pact to read the entire bible together, we may not have made it through Genesis. He very cleverly learned that if he broke a few dishes, he wouldn't be required to wash them.....grr/ When our baby brother got burned, we had to sit out in the car while Mom and Dad went up to visit, This was during those barbaric days when Mothers were not allowed to stay over in the hospital. I punched him in the nose and gave him a bloody nose. I always feared his retaliation, and when I asked him about it 15 or 16 years ago, he didn't remember it. Whew.
