When I come in, all must rise
When I go out, all low bows, but not to idolize.
When used over, I’ll do for a bit.
You likely have a diamond of mine, but I don’t need it.
You know Kelvin, he runs hot and cold, but he’s versatile
He runs left and right too. When he waves you simply must smile.
Many times I can be a bore.
I affect your mother to the core.
