What did you see that you definitely weren’t supposed to see?

Long suspected my dad, at the age of 13 and up, of possibly committing infidelity eventually considering how bad of a relationship my parents had, that is putting this long story short. Around 16 or 17 years of age, we are on Christmas vacation. Christmas. Vacation. Dad is sitting with his back to a mirror while he is on his iPad and we are watching a movie when everyone else in family is in bed (I am sitting in a chair opposite the mirror). I glance over at him and noticed in the mirror reflection him scrolling through photos of women. I have a pretty high moral compass, and also have zero respect for him basically at this point (he had been a pos for most my life), and ask him what the heck he is looking at. He says "I am looking at lingerie for your mom." "Ah." (I don't really believe him fully, it's super fishy). "Do we need to talk more?" "Nope." I initially thought he was looking at porn.

Fast forward about a year, maybe 2? Honestly life had been such a shitstorm it all blurs. Turns out he was cheating on mom, I wasn't surprised. Was seeing multiple prostitutes apparantly, but only claimed it was during this period of time, and that was only time. Yeah I call bs, but I think he was shopping for "stuff" for his affairs.

Merry Christmas! Here's another memory to suppress!
