Lunch Boxes

If each person takes one lunch to work each day, how many lunch boxes do you need?  With a bit of nostalgia, I miss the brown paper bags or metal boxes of old.  Now students bring Vera Bradley or Thirty-one lunch bags.   I'm ashamed to admit that I own five, and I'm the only person who totes a bag lunch to work.  Three were gifts from students (one even had an entire lunch in it the day it arrived), one has the name of my school and is a really good size, and the other was a promotional gift from some conference.  I gave one to my daughter who also teaches, the promotional one is going in the give away bin, and I'll have to think about the school bag.  Nostalgia is a tough one when decluttering.
