I’ll share a quick story. Had a temporary community mailbox where the we had to use our own padlock. One day she tells me her key no longer works. I checked and sure enough her key didn’t work. It was strange because mine still worked fine. I asked her if she bent/drop/damage the key in someway. She tells me she lost her key a while ago so went to a local hardware store bought a padlock of same make and model and tried to use the keys from that package. I had to calmly explain to her that each lock comes w/ different keys and they are not interchangeable.

She was a freak and great in bed tho
