Another logical idea

My kids lost the lid to their toothpaste down the drain, and try as I might, I couldn't save it. Our sink is rather old-fashioned I suppose, I and doesn't have those handy cross-bars part way down to catch things. Tala, now four years old, asks me, "Mommy can we just BUY a-nudder lid for it someday?" Ohhhhhhhhhhh I love my kids.
