setting a table

I was watching Yo-Gabba-Gabba w/ my son this morning and they were showing in a round about way how to set a kitchen table. Which got me thinking about how often do you actually formally "set" the table? I think the closest we get is to holiday time when we have to have everything set out. We don't do it nightly. Sometimes the kids will set the table for dinner, provided our favorite dumping ground aka the kitchen table has room for all 5 of us at the minute. And sometimes thekids are sort of a dine and dash.
