The vase problem

Two friends, a blonde and a redhead, are walking down the street and pass a flower shop.

The redhead sees her boyfriend buying flowers. Red sighs and says, “Oh, crap, my boyfriend is buying me flowers again.”

The blonde looks quizzically at her and asks, “You don’t like getting flowers from your boyfriend?”

Replies the redhead, “I love getting flowers, but he always has expectations after giving me flowers. I just don’t feel like spending the next three days on my back with my legs in the air.”

The blonde thinks a bit and says, “Don’t you have a vase?”
