My grandpa is almost 80 years old. He blatantly complains about stuff he doesn't understand but because he was once a big shot he think he does. He takes decisions almost as random as a 20 side dice but the numbers are just options and have no correlation among each other. Eventually he does something that seems to make sense, but if you live enough time with him you'll see that's by chance.

Wow, what's it like being the president's grandkid?

He was once president or something of a Country Club where he only let the rich to go. It was kinda lame cause he kept bullying some foreigner workers for no reason. He was in charge until people noted he was even more senile than the previous club owner

When I’m that I want my grandkid to think I am always right mysteriously and never realize it’s because I am past-posting.

>He takes decisions almost as random as a 20 side dice

I'll bet he knows it's a "20 sided die" though, or is he that dumb?
