Me too. My fondest memories were coming home to a fraternity house where 40 of us lived together. There was always something going on. What great times! We were either learning something new, hanging out together, playing football in the yard, playing bridge, fixing up our house, partying, chasing women, etc., etc., etc. Lunch and dinner served every day in the dining room. No shopping, no mortgage, no one depending on us for so much, and no cubicle!
I've been trying for years to recreate that atmosphere in my adult life, but without much success. I haven't given up, though...
