“Like your mum slept with randos and you and your siblings are all different halvsies…. Truth.”
Yeah, but I responded to going way back in the lineage, not anything contemporary.
Well, you obviously can't go "way back" if already your near-ancestors are "black boxes!"
No use researching dear old great-great-great-grandfather's sod-busting days in Minnesota if, in fact, your grandmother's 1930s neighborhood milkman was "very popular" back in the day!
