It's the Way My Mom Taught Me
One day a little girl was watching her mom make roast beef. Her mother cut off the ends, wrapped it in string, seasoned it and set it in the roasting pan.
The little girl asked her mom why she cut off the ends of the roast. Mom replied she didn't know why — but it was the way that her mother had done it.
That night grandma came to dinner and the little girl and her mom went to her and asked why she had cut the ends off of the roast before cooking. Grandma replied she didn't know why — but that was the way her mother had done it.
Great grandmother was quite old and in a nursing home. But the next time the little girl and her mom and grandma went to see her, she again asked the question.
Grandma looked at them a bit surprised and said, "We were poor and had a small oven in those days. I cut off the ends so it would fit."
