I meant to comment, now I'll have to answer my own question. My ultra skinny jeans!! I haven't fit into a size 3 since high school. I just can't throw them out!
Some things in my garage from when I had my shop. They should go but I keep feeling I may need them for something someday. For what? I haven't quite figured that out yet.
My mother-in-law, but I keep forgetting she passed away last year finally.
I have a couple of pairs of jeans that I know "someday" I will fit back into. Actually I am pretty good about getting rid of things. I have moved 15 times in 18 years, so packing and unpacking stuff you don't use is a pretty good incentive to get rid of it. With that said my husband has an entertainment center that has a bottom drawer that is broken. We moved it two moves ago that way because my husband wouldn't part with it. After our last move, I finally talked him into getting rid of it. He gave it to his brother. He can't use it either and we ended up with it again. Every time I try to get rid of it comes back. On day when my husband isn't home I am going to take it apart and find a dumpster and get rid of it. I think that is the only way it is going to go away.
The complete (original) Star Trek series on VHS tape in their original wrappings. A gift.
Quite old cleaning detergents bottles, empty ones. Think of making a collection some day.
