lol, I thought of that later, as I reflected on my semi-wild 70's youth. I said to myself, "I forget to mention beer", lol
I worked at a clothing store in the mall at 17 and 18. Had a gf working in the same store. Made about $90 a week, working P/T. Spent about $87 immediately that weekend- beer with the boys Friday night and date night Saturday.
It was school, work, beer and getting laid. It was not complicated.
