The oldest I've seen was 60s but they could pass as best friends they never did public displays they would just sit next to each other and talk.
My Babymama oldest sister was a stud ..looked like snoop from the wire.she drank way too much (trying to cosplay as nygga Drinkin 40s all her life)
She was always glued to the hip with her Wifey(fake ) "Barbera ann" .they been together damn near 10 years, and they did everything together, even went to the bathroom together..which I thought was weird...
Eventually the Stud died of Cancer and the next month Barbera Ann got into a relationship with a Nygga and got REAL married and was living her best life
Now that I think about it, they weren't even really old, just some Drunks that like to sneak and Geek crack rock...so they LOOKED older than they were supposed to.
My point is that ONE... might be a lesbian...the other usually just lonely, hurt or waiting it out cause she getting taken care of
