Because the question is extremely stupid, he should take an extra 10 seconds and it should be obvious
In which sense is this "obvious", hubert123? I am really interested in what the comment meant by "restricted to humans". Try to be explicit in explaining.
This breaks the HN guidelines about civility. We ban accounts that do that, so please don't do it.
You should also have better manners than to presuppose "he" when speaking of a fellow user.
