Boy, was I wrong about that! I always thought it would be so fun to have my dog along.
I was recently asked if I could do a very last minute babysitting gig for 11 hours. I told them I could only do it if I could bring my dog since I would be gone so long. They agreed. Everyone had a great time but me. It was as though I was taking care of an extra kid. They live on the 5th floor, so I had to time the dog's bathroom breaks so he wouldn't have to go when the child was sleeping. At home he sleeps a lot during the day, but there, he would follow me from room to room to see what i was doimg. It was just so much more to think about than had I just watched the three year old boy alone.
Well, I'm glad to not have that fantasy any more. If it happens again, I'll ask my elderly FIL to let him out on the porch in the afternoon.
