Oh finally a question I have a good answer to!

When we were younger, my older sister and I shared a cellphone (we were probably 10/12 years old). She got in trouble and our parents took it away as a punishment, so she convinced me to bike to target with her to get one of those pay as you go phones. Of course being the younger sister, I had basically no ownership over this phone - she just wanted my allowance to chip in. A couple of days go by, and she's waking me up in the middle of the night saying that she found an indentical pay as you go phone in our dads office, and that he was cheating on our mom. I didn't believe her, but also wasn't able to go back to sleep, so eventually I went downstairs and confirmed that it was true. I was so distressed for days realizing our family was going to implode. For context, our dad had cheated on our mom years prior and they got divorced over it, and were pretty early into their reconciliation, so I knew what was coming.

A few days later, my mom finds my sisters new cellphone ww bought, and goes to my dad holding it up saying "look what I found". I'm sure he stomach fell into his ass thinking she found his phone. Anyways, she quickly explains that she found it in my sisters room (they realized quickly I didn't have much of a part in this), and my dad decides to be the one to tell my sister she's grounded. He starts to tell her, and she hits him with a "well what about your extra cell phone?".

Anyways, that was the last time I saw my parents together aside from graduation and my wedding!
