One time, I went over to my sibling’s place to have a BBQ party. I met a distant relative who was my aunt. All was good, had a great time with a relative I have never met once.
When I was eating dinner, my mother explained that my mother-in-law, my distant aunt and my uncle’s wife were all sisters.
At that night, when my dad was driving home, as I pieced up the distant family tree, I realized one thing.
My eldest brother married my distant cousin.

TL;DR Went to sibling’s house, mom told me something, had a revelation that involves i*****.
