Occasionally I hear people talk about relatives who insist on getting to the airport insanely early.
Don't make me laugh, I think.
Your relatives are fine people, I'm sure. But in this regard, they are mere pikers.
My late father was the champion. He once went out to the airport before the family members who were flying that day had even finished packing.
Let me repeat. He was not one of those who would be boarding a plane that day. He just wanted to get an early start on being in position to say goodbye out at the airport.
