Grandfathered

When you slide into someone’s DMs that you had a crush on but haven’t seen or spoken to in 30+ years.
Me: You remember Christy from high school?
Friend: yea, You crushed on her bad
Me: I grandfathered her last night on Facebook. I’m still crushing on her.

The Grandfather Effect

An term made by me at 3 am looking at minutephysics video about the grandfather "paradox"

The Grandfather Paradox is when you go back in time and kill your grandfather but since your grandpa is dead, you cant go back in time since.. u know... you dont exist. But since you dont exist your grandpa exists which means YOU exist but then you go back in time and kill your grandpa, and it keeps going on forever.

But in minutephysics video he talks about how it´s NOT an paradox (cant have links sorry)
Me: Have you heard of The Grandfather Effect?

Friend: No. What´s that?

Me: The definition is: If an action makes that action impossible, that action is both possible, and impossible. - Me 2020, it is kinda like Schrödinger's cat.

Friend: Ok, i understand now.
