Idk, my step dad met my mom in the 90s by taking out a personal ad in the paper. It said, in full (minus A/S/L and contact info):
“Can’t dance, won’t cook, never had a job. Frog seeks princess.”
He was a resteraunt manager back then, idk if he can dance tho.. probably not. So it can be done in a text-length message. It’s rare to find a good match that way though (and they weren’t!), because it’s very little to go on.
