I don't care who you are - happiness looks good on everyone. I love the feeling of smiling so much that your ears hurt. Yeah, you thought I was going to say cheeks. But, I'm weird like that, and smiling so much makes my ears turn red and get so sore. But you know what they say, no pain - no gain.
SO go on. Be happy. Smile so much it hurts. And if you have any good jokes - send 'em my way!
