Spiders are bugs

In fifth grade grade I confused my teachers with my large vocabulary. Sadly my open-mindedness is not equal. I hate to be wrong. I have less arguments now, but that is because I know more; I have more information and more skill in presentation.

At the Rock and Gem show I saw a trilobite and said 'cute bug'. The seller was offended and explained that this wasn't a bug, it was a trilobite. I felt incredibly stupid. Bugs have always stumped me. Spiders are not bugs, those weird sea creatures are not bugs, worms are not bugs. I was never much of a bug-enthusiast, so to me it was just a misunderstanding of definition.

And it was. I encountered the bug obsession again today. I looked it up. A bug is an insect or insect-like creature. To me a spider is insect-like, and so is a trilobite, (manner of locomotion, tendency to segmentation, etc.) So hah! Spiders are bugs, disagreement is simply a matter of definition, not scientific truth of leg numbers and segmentations. Pardon my vindictiveness, I don't like being wrong.
