I lived in a townhouse before that shared the stair wall. The neighbors kid couldn't have weighed 40 pounds tops, but sounded like he wore lead shoes. Never again, i would live in a shed in Avon, NC (BTW I saw a guy that did that and was little envious)We bought a house and converted it into a side by side. So it’s like a duplex but side by side .. didn’t know the walls would be so thin!
