So you are addicted to cats (Catolic) and you're not a gay doctor (Orthodoc)? Well , Im not from English speaking country so my english is not perfect then you weren't an atheist. simple as that.
I was just playing with words. xD When you're not sure about a word spelling go to Google and type this: define: (your word) Example : define:catolic Google will give you a suggestion like this Showing results for define:catholic Then you know you misspelled it. Now try define:Orthodoc and see what happens.
