Input: Text: so i was at a supermarket with my girlfriend and, since i was doing the usual unhelpful male things i got sent off to find a cart. i had no idea where the carts were kept, so when i saw one apparently abandoned i just grabbed onto it and rolled it around the corner. it was about ten seconds before i realised; the cart was not empty. 

there was a single green bottle of shampoo. that was about all that registered before my mind went into a sort of panic at the thought of trying to explain to some angry and confused shopper why i had just taken their cart away. there would be no way i could explain it away without, at best, being revealed as a lazy, unobservant idiot. i didn't know what to do. i couldn't take it back. i couldn't take it to my girlfriend. looking back, the clever thing to do would have been taking the shampoo out, but i was far from thinking clearly by this point.

the only solution i could come up with was to ditch it. i darted down an aisle and, as nonchalantly as possible, let go of the cart and kept walking. i saw it later on in the same spot, the same bottle of shampoo inside it. i can only imagine the owner had to fetch another one.
