Me: I want to be in shape enough that when I am walking with a tall person, I won't be huffing and puffing to keep up with them. I want to walk fast!
My Friend: Yeah someone will ask you "Why are you walking so fast?" and you can say "This is a fast world and I am tiny".
Back History: I am only 5'1" and it is hard sometimes to keep up with people who are tall and walk fast!
