'Tell my daughter how you know what I was doing last Saturday night.'

'Better idea, son in law, let's tell her that funny story about the time we ran into each other a whore house.'

it's a powder keg waiting to explode in the son in law's face.

i've actually been in a similar situation at a bathhouse. i was in there and was all worried about who'd see me while i was there. and then i did see some ppl i knew - casual friends who like to gossip, even. and i realized that they had nothing on me b/c they were in there too. anything they said i had a perfect comeback. in that moment i understood why i'd not heard any gossip about so-and-so being in the bathhouse. b/c how did the reporting person know unless they were in there too? so what shade could they throw?

same thing here. the father and son in law have nothing on each other. they might as well bond over it.
