all sorts of things are possible… i feel like i would remember a fling, but i have been fully blacked out before… i always had friends there to tell me stories of how dumb i was, so i probably didn’t father any kids i don’t know about….
but if some kid showed up out of the blue id be skeptical, hire a private detective and get extra third party testing…
well i would if i had enough money to be worth suing over….
