funny and sad

I saw this cartoon from xkcd on Jim's blog. I thought it was really funny. I don't know why it is that some people feel so obligated to point out when they don't agree with someone else. Especially on the internet. I mean, like, if you come across something that you don't like or don't agree with... there's a little "x" in the top, right corner, and if you click on it the whole thing goes away. But I know people who are like this in person too. Anything you mention, and they'll point out everything they don't like about it. Like if you're reading a book, why is it that some people will only discuss what they don't like about it, rather than trying to find something they can learn from it? My philosophy is - I can probably learn something from just about anybody and everybody. But that's me. I have a lot to learn. Some people seem to think they just have a lot to teach. (And apparently I feel the need to tell them they're wrong. Ugh). In an unrelated thought - I might not get outta the bathrobe today.
