I had a situation kinda like yours. My kind-of sister had it so my dad and his fellow-fathering crew had her come over and spend time with us kids. It was dumb, looking back. Like eating poison ivy to gain immunity haha what were we doing?

edit: apparently vodka and duct tape is also not the most ideal way to deal with deep lacerations either. Glad I wasn't a parent in the 90s (also glad I have access to therapy and birth control otherwise my arse today would probably get CPS called if I did a fifth of what seemed to be common back then)
