Me: So if we imagine the Milky Way is a CD, the nearest galaxy to us, would be another CD eight (8) feet away.
Girl in class: So is that eight feet of CDs or eight feet from me to you?
Me: What do you mean?
GIC: Is that eight feet of distance or like, two CDs equal one foot, so it would be 24 CDs away?
Smart Student in class: Eight feet is eight feet.
SSIC: Eight feet equals eight feet of CDs. Eight feet will always equal eight feet.
GIC: Oh. What? I'm confused.
Me: What is heavier, a ton of feathers or a ton of lead?
