Yeah, those things DO have a way of nagging at ya! LOL
When my oldest was a baby, we were shopping at JCPenny and she was in her stroller. When we got back to the car I took her out and she was holding a toy she must've grabbed in passing and I didn't notice. It was freezing out, I didn't want to take all of the kids out of the car and go back, so I didn't, I just went home, figuring it was an accident and no biggie.
Well, it kept bugging me, and I ended up calling them right before they closed and explaining that the baby grabbed it and I didn't notice (she was about 8 mos., so it wasn't like she knew what she was doing) and ended up paying with a credit card over the phone.
If I wouldn't have, I'd probably still think about it and feel guilty. I shoulda done it right away, but too late now, lol!
