I know why you are strong⁴¹

One day I was walking in front of my house and also exercising at the same time. The old German lady who lives on our block — the one who has the dog — came up to me and said, “Now I know why you are very strong and why you are very skinny.”

Then she came near me and pushed my left shoulder. Whenever she sees me, she always pushes my shoulder in an affectionate way.
