I have a slight dilemma. My alien has two eyes, but I know if they were to have one eye they might have difficulties with depth perception. Unfortunately they only have one ear. Does that mean they keep shouting in people's faces? I would prefer it if they did not bellow every passing comment, but if that is the price to pay for the one ear, located centrally on their face, like a glorious ear-nose, then that is the price I will have to pay! Thoughts?
