We had an outhouse til I was about 3. Even after we got modern us kids used it so we didn't have to go in the house.
That was back in the "olden days" when kids actually played outside all day!
I remember those days....I would hit the front door at about 7:00 AM....and other than meals...not go in the house until after 9:00 PM...
BUT, we DID have to go in the house, we weren't lucky enough to have an outdoor bathroom....LOL
