I feel your pain. There are certain things we learn to deal with and what my husband and I call 'bad aim' is one. Pinot has a little trouble with missing the box, too. We do find if we're away, or if there's disruption, it's a bit worse, but we can pretty much count on it at least a time or two every few days.

I wish I had sage words; I do not. We love them, we coat everything in plastic and clean up. Good luck!
