If you went through your cupboards or refrigerator would you find food you didn't even know you had? Do you have expired food hanging around?
We have accumulated a lot of chips. Opened chip bags that are brought home from my parents' house get forgotten as they are tucked away in a bucket. I let the kids eat chips after school today to see which chips are still good. We threw away one empty bag of Smartfood popcorn after the kids finished it off. That was my decluttering for the day. :-)
