Some time ago, I decided to raise my own tomatoes.
So I planted some, watered them, and kept the soil loose and free of weeds. The plants grew tall and then they bloomed. Before long they had little green tomatoes all over them. In time they ripened and I had tomatoes to spare.

So the next year, I decided to raise my own potatoes. I planted some, watered them, and kept the soil loose and free of weeds. The plants grew and then bloomed, but they never had any potatoes on them.
