I'm good at making numbers, but when it comes to decimals, I'm a no-go.

Me: Hey, you know how when people say 'You're the sun of my life' they basically say that you shine their life?
Jimmy: Yeah?
Me: Well, how would you act if there was a boy that was like 'Would you like to be the sun of my life?' and this girl says 'Sure!' and the boy says 'Ok, so stay 1.1989..6..5...7...1......9.........1919 meters away from me!'

Honestly, why?
