There are times when something known for good, ain't so great.

Knocking down all Ten pins with one ball while bowling is good, a Strike. When someone say's "She's a Ten" you can picture in your mind what she should look like (taste's do vary here). Window's 10 is suppose to be really good, I personally can't say, I don't run it.
When you are asked to rate something it is usually on a scale from 1-10, Ten being the best.
When you get up in the morning, step outside and the thermometer says "10", not good. Ten sucks. There aren't many things worse, 9 to 1 and the minuses of course but let's face it, after a certain point less means nothing. At 10 degrees you are cold, your nose hairs bristle, fingers cramp up, muscles tighten, which is the same at 10 below, you cannot tell the difference between 10 and -10. Actually the only good thing about it being 10 and below is that you can't stay outside as long as you can when it's 32. So at least there's that, the colder it is out the less time you can stay out in it, so you are back in where it is 70 or so.
