Thinner than water?

One of the things that's shocked me has been how well Ross is getting along with my family. Since I really only see my extended family every four years or so, it's kinda a given that they'd treat me like a king. Ross has been getting the same treatment. But ionly took my grandfather a week to scare him. After a few too many Royal Challenges, he started challenging Ross on when he'd called his parents last. When Ross said he'd e-mailed them, Grandpa exploded that "voice and e-mail are not the same thing!" Then he made Ross dial them up in front of him.

"I am a father too, you see."
"I know, I uh, know your grandson quite well."
