My family knows, my work mates know.. I'm not really hiding any of it.. I treat it as a hobby like any other hobbies.. I find if you try to hide stuff then people assume it's dodgy. If you are open about it, they tend to find it maybe a bit strange, and maybe funny.. it might also not be their thing, but it's perceived as harmless, as such.
Like.. have a fursuit, hide in your closet for days on end wearing it, but never show it to anyone, or try to obscure it.. and you're a creep. Wear it, stride around in it, go onto the street, wave at people, and you're cute and funny.
Hope that makes sense ^.^
