I was being facetious, don't get angry. Speaking of that though, did you know that ancient taxonomic theory describes birds as having red breast feathers, lightweight bones and as having the ability to sing. How does your ostrich measure up to the bird standard?

Nonsense, according to taxonomy, whales are mammals, because they breathe with their lungs and they are viviparous, don't think you can fool me.

I wouldn't dare, it's just that recently I've been reading some cognitive linguistics literature and I just thought it was interesting is all. Like you said, the model bird in classical taxonomic theory takes the robin as its prototype.

So I should make a Chinese definition of a bird along the lines of this classic taxonomic theory.

Frankly speaking, although every day we classify the things around us, it's not really that easy to verbalize all the classification standards we have in our minds!

Don't bother, there have already been new developments in taxonomy, if you're going to do something, you should use the new methods.

Hey, that garbage can sorts waste by type. You put it in the wrong spot! Banana peels are non-recyclable.

If everyone didn't separate recyclable and un-recyclable waste like you, what would be the point of these special garbage cans?

That's because our residential area doesn't separate trash. Don't I always put used batteries in the special recycling box? And don't I collect old newspapers, beverage bottles, pop-top cans and such and sell them to the little old lady who collects garbage in our residential area?

Wow, you know a lot! I've never seen him separate the trash in our home.
