Have You Ever Done Something that You Regret

Yes.  I was at a store with my mother, and she told me to take my little siblings to get an item from a isle.
After I had returned with the item, my Mom realized that my siblings were missing.  I ran back to the isle that I had just left, but they weren't there.  I ran around the whole store looking for them, and when I finally went back to the isle that I started in, and they were there.  I took them back to my Mom, and she was very relieved.  I regret that I didn't pay better attention to where they were.
