Unlike my last post here, there is no information in the above signature that certain people wouldn't understand, so I can simply express my own opinion.
A lot people who watch The Land Before Time see the characters' feelings and simply observe them, perhaps undertstanding, but are often not personally effected. This signature expresses that he doesn't just feel for the character but with the character. There is such a connection between the writer of this signature and the character Chomper that if Chomper isn't feeling so well, he feels bad too. In the same sense, as in the example from the signature, if he sees that Chomper is feeling good, then he generally feels good as well, indicating that "The Lonely Journey" must have been a very horrible experience for the writer. It shows what a sensible sharptooth thinks: leaf eaters provide the nutrients their bodies need to survive, like protein, for instance. Unlike many sharpteeth who seem to be unfairly portrayed as actually wanting to just kill everything for pleasure, this is the moral way for them to think. The signature is saying two things. You can feel the same way as someone you care about, and that sharpteeth aren't murderers because it isn't their fault that their bodies were designed to need flesh to live. If sharpteeth didn't need meat, they wouldn't go around killing, hence it is for survival, not the thought of ending life. Considering how well it was written, how there were no mistakes or faults found anywhere in it, and how deeply it was thought out, I give it...
Now hold on one second! Most of you think that I'm just going to give him a perfect score to repay him for giving me one and the compliment. Think what you will, but unless you disagree with the reasons in my evaluation, I don't think people should start assuming that I simply do good things to those who do good things to me. Even if he had given me a 1/10 and said he thought my signature was an abomination to this site, my evalution wouldn't magically have different facts that say his signature isn't a good one. But whatever you think of me, well, I still give the above signature a ten out of ten for the deep meaning and the way it was written, and how the significance of having a bond with someone will allow feelings to be shared.
