I have spent the majority of (almost) 30 years making weird faces.
Sometimes, I make weird faces because the sun is in my eyes:
Other times, I make weird faces while I’m talking. (Though I must admit that my father-in-law is making a MUCH weirder face in this picture than I am .)
When I was six, I made weird faces because I had no front teeth:
With each tooth I lost, I felt that I looked more and more like a vampire. So I began posing like a vampire. (Which explains why this expression was sometimes accompanied by a hiss.)
Thankfully, I do not make this face anymore. Because if I did:
-I would not have any friends.
-I would not be married.
-I would be able to get a job.
-I would be forced to live out of a box.
Unfortunately, now that I am older and my teeth have all grown in, my weird faces look more and more donkey-like:
Good thing donkeys are more socially acceptable than vampires.
