Nobody deserves to be punished for a crime that they didn't commit. But we all know life isn't fair, and that includes the so-called "justice" system. Innocent people get punished all the time for crimes they didn't commit—in courts-of-law, and also in relationships.

A pair of my wife’s panties fell out from the leg hole of my pants while I was driving to work. I grab them and shove them in the driver side door pocket and promptly forget about them. Several weeks later we are cleaning out our cars together and she finds them and is like WTF. She doesn’t recognize them as her own. Finally remembers after I scroll through several thousand of my pictures to find a pic of her actually wearing them.
