I live in a 100-year old house. The bedrooms had no closets originally. They were in the hall outside the rooms. (There are closets built into the bedrooms now, but clearly not original.)
When my kid brought home bedbugs from a sleepover, I understood why. Much easier to cope with the cleanup in the pre-pesticide era if you didn't keep your clothes where you slept.
@EileenKCarpenter This house was, I'm guessing a little younger than that. I live in a post WW 2 home. Two bedrooms, mine is smaller, and a Jack and Jill bathroom but luckily it's just me and my mom. The people who lived here before us slept three boys in my room. My grandparents lived in an old home and had 6 kids. The 2 girls got one room, 4 boys the other. Grandma and Grandpa on a pullout couch. Grandpa worked nights too.
