As far as freezing stuff, we don't because we never get around to using it again. A couple of times we bought the large packs of chicken, used a couple of pieces and froze the rest. We never got around to using them. We don't like laying food out in the kitchen before work or even overnight.
And yes, I am very weird about food. No leftovers after 2 days (36 hours), and that makes it tough to cook since it's just 2 of us. We strictly adhere to dates on packages (I tossed out a half box of zingers this week that expired June 16, and my coworkers went nuts about that because they said they weren't bad even though they were a month past the date on the box). If something smells/tastes bad or is green, it gets tossed.
If we ever buy fresh fruit/veggies, we'll eat on them 3-4 days at the most, same with milk. Just stuff like that. Trying to be as safe as possible. I did keep my loaf of bread I brought to the office this past week for lunches next week. I will just take 2 slices out of the freezer every day, toast them, cut the edges off and make me a PB&J or tuna sandwich. So that, I believe, is a step forward (the fact I'm eating bread more than a week after I bought it).
