Yes. A day to show appreciation for mothers...and those who have been like a mother, to someone.

A celebration of people who mother. That can be anyone.

Everybody wants to be a "Mom" until it's time to make me a lasagna .

It certainly is! and no guy better ever forget it.

You're forgetting the biggest factor here and it's not that you are right and have vast reams of evidence to call upon to prove it.
You are arguing with a woman.
You can't win Darth.
But this time when you get struck down you won't become powerful, you simply won't visit the cat.

If you didn't come out of her and you didn't put a baby in there then it's not her day with you

She has to be a mother

At least it is not next month, when it will be Mo Fo's day.

Mother's Day all the way!
