....the dinner table?
As kids, every dinner was at the table. Now that I have my own family, we eat at the table only on occassion, mostly weekends when I grill out, or Thanksgiving/Christmas meals. We have a countertop with barstools that serves as our primary eating area nowadays.
I do remember it being a huge deal when my dad would allow everyone to eat on TV trays in the living room for dinner. Usually there was something big showing on TV (like the MASH finale).
