Consider a balloon. Uninflated, make a mark on opposite sides, and then make a third mark right next to one of those. When you inflate that balloon, the two points on opposite sides of it become farther apart because of the stretching of the whole balloon, but the two marks right next to each other don’t become nearly as far apart, because they are only experiencing “local” expansion.
Crude, yes. Fair, no.

I wanted to make a fart joke.
But I like your balloon explanation. That makes sense to me.
We must sometimes succumb to our basest instincts.
Don’t you mean our basic stinks?
Ok I’ll stop.
