It's not that monkeys don't like seflies, because they obviously have no idea what one is. What they definitely don't like, evidently, is humans invading their personal space while looking away and yelling "smile!" That can at least be said for the little monkey in these shots, who took exception to being used as a prop in this woman's vacation photos.
Many wild animal selfies turn out fine. Others start out fine before going horribly wrong. This one looks like it was destined for failure from the beginning.
