As if there was ever any doubt.
Yesterday I went out with MIL, SIL and FBIL. MIL and I went shopping while SIL and FBIL went to get her cellphone contract sorted out. MIL has some issues with her back and legs, so she grabbed a cart as soon as we entered the mall, and all our (mostly hers) shopping and everything went into that. We were halfway through the mall when she realized that she still had grocery shopping to do but the cart was full already, so we decided that I would take that cart while I went off to look for PJs, and she would get another cart at the grocery store.
I didn't find exactly what I wanted in Shop A but there was something close-ish, so I moved on to Shop B knowing that if I didn't find what I wanted there I could always go back to A. While looking around in B, I found these sets of temporary hair colour chalk and SIL had been talking about getting temporary colour in her hair, so I put two in the cart, and carried on looking around for PJs. Didn't find what I wanted at B, so headed back to A. With the chalk still in my cart.
When I got to A, FBIL came up to me to say that they were still busy in the cellphone place, and would I be much longer/where would they find me etc. That's when I looked down at the cart and saw the chalk. I nearly fainted. I immediately asked FBIL to hold the cart for me and ran back to return the chalk.
Thankfully there were no consequences for me. The guard just took the chalk back and was like "It's okay, but try not to do it again."
I think my brain just took a holiday yesterday, because I also very nearly left the cart in Shop A when I went back.
So... Totally unintentional shoplifting. Who else has done it?
