I'll have to admit that I did...
We were in a discount store once (like T J Max, sells last years stuff, etc...), shopping about an hour from home, and it was chilly... I slipped on light zip-up chenille type sweater to keep warm... And after quite some time shopping, forgot, and walked right out... tags and all!!!!
You know what, I never got back over to the store and like go in and pay for it.
Maybe I thought I would just be embarrassed and mortified.
And, I LOVED that sweater...
As old and stretched out and ratty as it is, I STILL have that thing.
Wish I could another find one like it today, and would be happy to pay good money for it!
