I have old family pictures: my great grandparents sitting in chairs in their yard, the corn in their garden growing in straight rows behind them; my grandfather, white shirt, dress pants, wearing a straw hat and grasping the handles of a plow behind an old mule in the middle of a partly plowed field. (I'd really like to know the story behind his clothes). I have a more recent picture of my uncle standing between stalks of corn taller than he is. I suppose I could dig a little deeper and find more of them.
It might have been where I grew up, it might have been the era, but I always knew if I wanted food to eat, I was supposed to raise it, and if I wanted color in my yard, I had to plant flowers.
Maybe it's genetic, you think?
