Not a coffee maker
- Do you know what I got for my birthday from my wife?
- A coffee maker?
- Nope. Three line segments that measured 1, a, and b.
- How thoughtful of her. I guess you didn’t have them already.
- You are right. It made me extremely happy.
- How long did the happiness last?
- Till the next morning.
- What happened then?
- She asked me to make a line segment which measured a times b.
- I would have preferred the coffee maker.
