201/365 (This Bio Chapter...)

You can really tell someone's maturity level and/or certain aspects of their personality based on how they react to an "Animal Reproduction" chapter. The super immature ones refuse to look at the pictures diagramming the female and male reproductive systems, and burst out into nervous laughter whenever sex is mentioned. Which, in a chapter like this, is pretty much every other sentence.

On the other hand, the ones who want to seem better than everyone else are the ones who keep an absolutely straight face throughout the entire lecture, never laughing except for jokes thrown in by the teacher, and shoot disapproving looks at everyone when the laughter simply cannot be contained.

Oh, the things that can be learned from a bio lecture that have little to do with the material being covered...
