My friend just pointed out the fact I could probably eat a year without going to the grocery!
The reason I keep so much is because each week I invite a needy family to dinner and most of the time send them with a box of food too. I started this tradition when I was 18 and a teacher paid for 6 months of a apartment for me because she knew my family and I had been homeless for the last 3 1/2 years. When I first started it, I was only inviting people every other month and not giving them a box of food. Now that I am married, have a college degree and a well paying job I do it more and plan to always continue.
