Moved out of my mom’s house when i was 18. I was roomates with friends and cousins who were my age. I don’t see my kids moving out of the house at 18 other than going to college.
18, moved to a little place in Santa Monica with two others from my Catholic girls school.
Then we moved to a beach house in Malibu that one of their parents owned. I hated driving from Malibu to LA almost every day and moved back to LA.
