We just had my sister-in-law and her son visit for a couple of days. Oh, and their dog. Let me just say that the house is quiet for the first time in over 48 hours. There's dog hair on the living room carpet. The floors aren't too covered in crumbs, thanks to said dog (a quite civilized beast). I see dust and hair balls everywhere, and you can't move without knocking over a LEGO brick or stepping on a rubber boot! The kids had a blast playing together, and we had a good visit. SIL is easy going and pitches in--she actually vacuumed and helped pick up the day they arrived.
My precious little fur babies, though, were very happy to see the tail end of the dog! (finally able to relax)
