How long is Forever?

This was the discussion after we got our flu shots yesterday and sported matching metallic silver band aids.

Madelyn: "I'm gonna leave this band aid on foreber, and foreber, and foreber. (she pronounces the v with a b). How long will you leave your's on Mommy?"

Me: "For a little bit longer."

Madelyn: "Well, I'll leave it on foreber. I'll take it off before bedtime."

Me: "Me too!"

So how long is forever? Aparrently to a toddler, forever only lasts til bedtime.
