I've compiled a short list of things I just have trouble understanding:
1. Kaleidoscopes. Clearly a fruit of the 1970's

psychedelic time warp, but seriously, what the heck are these things? I once met a lady and her husband who's sole job is to create kaleidoscopes and stained glass. How can there be a business in this? If someone put that much time and effort into producing something practical, the world would certainly be a much better place. Third world countries are in need of clean water and shoes, and here are the Americans making intricate toys out of multi-colored glass. It just doesn't seem right...
2. Negative dispositions. Some people are just the stereotypical "glass is half empty" type of people. They wake up on rainy days and grumble about the rain. They get their coats stuck in the door and furrow their brow and sigh whilst violently tugging at it. They wonder why bad things always happen to them. They complain. Constantly. To their defense, most of them were raised that way and learned the behavior from their parents. Plus, their place in the world helps others to prepare for the worst and I admit, there is some value to that. However, as the half empties can probably attest, it is a terrible way to go through life - always focusing on the negative. It brings the positive people down, slowly draining them of all things happy (like Dementors). I just don't understand it. Unnecessary.
3. Leashes for children. I know, at least one of you out there reading this is a leash kid. You know what I mean, the fluffy, animal-shaped backpack looking things that are cleverly disguised vehicles of shame. Not only are these embarrassments to the establishment of parenthood, but they shed light on a deeper issue of Americanism: laziness. In my opinion, if you can't keep track of your kid, then you shouldn't take them to places where you might lose them. These are children people, not pets, and should be raised accordingly. Maybe eventually they'll make a Baby Bjorn big enough for toddlers...
4. The allure of pine cologne. While driving on the freeway today I smelled the unmistakable pungency of pine. I have no idea where it was coming from, but as it seeped into my car's interior, I couldn't help but think of how unappealing it is. I just can't explain it. About the only time I am okay with this scent is when they are packaging up my Christmas tree at the tree lot. What possesses some men to spray this all over themselves? This phenomenon is quite similar to the women's perfumes and accessories that smell like baked goods - just completely unnecessary.
