A couple months ago my dad finally hooked up the washer and dryer in my downstairs apartment. In order to do that, he had to cut out a hole in the wall for the dryer vent. The hole led to the utility room adjoining the wood shop Waltz is always trying to escape into, so of course he had to investigate. It amused me.
After his little investigation, the hole held no more interest and my dad and husband were able to get everything all fixed up without any help from the little fuzzy one.
