Brother: Do you know what I’m going to give Mom for her birthday? A beautiful cut-glass flower vase.

Sister: But she already has a beautiful cut-glass flower vase.

Brother: No, she doesn’t. I just dropped it!

Sister: Did you tell Mom you broke the vase?

Brother: Yes. I said, “Mom, do you remember that vase you always worried that I would break?” And she said, “Yes, what about it?” And I said, “Your worries are over!”
