smile

You're never fully dressed without a smile! 

Smiling is the universal sign of happiness. It's also very contagious. Whenever someone is smiling or laughing, you can feel that muscle around your mouth starts to pull up. Unless... the smile is totally creepy. 

Hopefully, you'll have more genuine smiling glancing your way than creepy ones! As for the smiling animals below, we got a little mix of both!
