What if...?

Everybody makes mistakes. All of us made at least one decision we wish we never have made and we would try everything to travel back in time to change it. But since that is not possible yet, we ask us one specific question. What if? I made a wrong choice without even knowing that I actually screwed up. It was a stupid mistake but it happened and I had to deal with. I wish I would have never done it. So this is the moment I regret the most.
