Within a year of my birth, my families normal changed a bit.
Before that time we had 3 generations in one house.
My grandmother, My aunt and uncle and their son, and my father and mother and their 3 (before me) kids.
It was a big place. On the first floor a third of it was a big kitchen and really big table, a third was an office and workspace, and a third was a diner. The upper floor had private suites. One was a sitting room and bedroom for my grandmother, 2 adjoining bedrooms for my aunt/uncle and their son, and 3 adjoining bedrooms for my mom and dad 2 brothers and sisters. There were 2 bathrooms, one at either end of the central hallway. It was on our businesses property. When I came along my father built another smaller house on the same property, and we moved probably 50 yards away.
Eventually that big house got torn down, and it was replaced with a building with the store and offices on the first floor, and 2 separate aparments, a one bedroom and a 2 bedroom, for grandma and aunt uncle and son.
There was another house on the property that had been divided into 3 separate units, like townhouses. When one of my brothers married he moved into the biggest unit with his wife. There was also a little bungalow plomped in the middle of it all, and my cousin lived there for a while.
So, my normal until I left home at 19 was being able to see everyone's home just by looking out the window.
Prior to all that, when my mother and father first married, they lived with his mother and father for a few months, while he built a house on a double vacant lot he bought with their wedding money as a down payment. They moved in, and after work and weekends he built another house, he sold the one they lived in and moved in the new one. With the money he bought another lot, build, move repeat until be had done that with I think 4 houses on that street.
That was back in the day when peope did that really stupid thing of giving the bride and groom money as a wedding gift, so they could get a house. Boy was that dumb, huh?
