Have you (or your child) ever accidentally taken something out of a shop without paying for it?
I have done it twice that I can remember, the first time I was in my mid teens and picked up a dog lead, I was walking around the shop twirling it around and then it was time to leave so just walked straight out with it. Got about 10 steps out of the shop, realised and took it back.
On the weekend we went to Toy world and I had a drink in my hand, my ds handed me something he wanted and when I went to pick up something else to look at it I placed the first item into the hand with the drink. Put the 2nd item back, looked at some other things and then walked out of the shop with the 1st item in my hand. Got a couple of shops away and went to hand ds his drink and realised I still had it made hubby take it back. Thank god no one saw and thought I was stealing anything. I can only imagine the amount of times they have heard 'oh I forgot about it'!!!!
