** Most likely with the arguable exception of Spike who seems to wander this strange line between pet, little brother, indentured servant and friend the animals are not her peers. Even if they are sentient they still don't matter in quite the same way as ponies do. It's like how some children are perfectly chatty with adults but quiet around kids their age. No adult is ever going to invite them to a sleep over or make fun of their braces. Similarly some of those same kids can easily give speeches to large crowds because there is a world of difference between a crowd of largely nobodies watching you and being one on one with Chris. Similarly Fluttershy isn't going to die alone if every dragon on the planet shuns her.
