What's the best thing you kept from one of your exes?

An unreasonable hatred for everything to do with alcohol, and a blanket.

I had a nice Bluetooth speaker for a bit, but it stopped working, so now it's mostly just the raw internal wounds.

Diamond earrings from one. A purse in the shape of Luna from Sailor Moon from another.

just the raw internal wounds

Ahh, the one thing that defines us all in sweet inevitable misery. Like balm for your soul!
