Dear Robo Vac,

I am sorry I can't let you glide along my carpets. You've been so good to me, since you arrived on Christmas. Really, I did take all the time this a.m. to move things around so you'd have a clear path to do your work. But my children unplugged you so they could plug in their karaoke machine. Don't worry friendly vac, me singing to Demi Lovato will make the carpets look better.... but I might just try it.
