ELI5: Why do photographs look so hideously wrong when 'flipped'?

It can't just be me - fairly often my phone flips a photo after I have taken it, and suddenly it looks awful to me. Why is this?

If you're talking photos of people, it's because our faces aren't symmetrical.  So when you see a picture of your friend, you see them in the picture how you see them in real life.  When the picture is flipped, you see their mirror image.  It's also why people think they look odd in photos, because you are used to seeing your own mirror image.
