I think I'm mostly a fan of the animal because of their personality. Kinda goofy like me :)
I cannot claim to know much about the animal, but I can help direct you to a site that might:
National Geographic Informative on Giraffe.
Also, I have found that they fight in an extremely odd manner that I tend to duplicate with my friends.
WARNING: Leads to headaches eventually!
In my opinion, giraffes have it all figured out. They are fairly relaxed animals; they seem not to have to many worries. If they do end up in a conflict, they solve it and carry on with their lives. Not much can effect their demeanor, so in a way, I try to emulate the giraffe and that is why I chose this animal for my blog.
