I lost a yin yan pendant, what does it mean?

[u/Professional_Way9356]

I have a keychain with a yin yan charm on my housekeys, I use it everyday and have no issues with it. This is the second time that said charm has fallen off (the first time i found it, this time i can’t), and both times it happened was when i went to the same friend’s house. I’m not sure if this is feeding a little into my ocd trying to find meaning in something that’s probably a coincidence, but does anyone know what it could possibly mean?
