A Little Incident While Shopping

Went shopping today. I only planned to buy one thing, but while browsing, I ended up grabbing a few more items. When I got to the checkout, I realized one of the items wasn't what I originally intended to buy, so I had to go back and put it back on the shelf. After rejoining the queue, there was only one person ahead of me, which was a small stroke of luck amidst the misfortune. On the way home, I remembered I'd forgotten to grab the item I actually needed, so I had to go back one more time. What should have taken a few minutes ended up taking quite a bit of time.
