Fluid Expansion

An actual quote from the girl, while looking over a question on her homework on thermometers:

 "Yes mama. I KNOW what fluid expansion is, it's not like I'm six you know!"

What she was trying to ask was why did the portions of the thermometer look like they were out of scale with each other. I thought she was asking why the numbers increased as they went up the thermometer.

My days are numbered.
