We keep too many plastic walmart type of bags. But I only keep some for two reasons. One, is they work fine for our smaller trash can bags (have 3 bathrooms upstairs where this works out fine). Also, for dirty diaper bags. Not long ago, we had 3, sometimes 4 kids in this house in diapers, so I double, sometimes triple wrapped those poopy diapers in walmart bags. I take the trash out once a week (we live in the country, no trash service here), and can't stand poopy diapers stinking up our large tash can in the kitchen area. triple wrapping poopy diapers prevents the stench. But we are now down to 1 kid in this house who is in diapers (he is 1, so will be a couple years before this changes), so with only 1 kid the need for 200+ plastic walmart style bags is overkill. I get rid of a bunch of them in our trash weekly, as we have way more than we need at this point.
But there are bigger problems in life and marriage. I can handle this one with little to no stress. I won't go in to otherr areas of WTFness that the woman does on a daily basis.
