All of us sometimes do things that we regret—we're only human.
Most of these things aren't detrimental to society either. They're everyday mistakes, slip-ups, and embarrassments that seem terrible in the moment, but hopefully don't end up following us around for the rest of our lives.
However, social media has given us the ability to give our public mistakes immortality. If a picture is posted somewhere, even if it is deleted after, it exists in the world wide web forever and ever.
Not trying to be your parents here, it's just the facts.
