There is only one species, or kind, of giraffe. But not all giraffes are the same. There are eight different groups of giraffes. Each group of giraffes has a different coat pattern. The pattern is a clue to which group a giraffe belongs to.
This is really what happens to me when I wear heels.just standing one second and then the next Im down<<< same. I've got weak ankles so I avoid wearing heels except for on special occasions so this doesn't happen all the time.
