“Never frown, because you never know who may be falling in love with your smile.”
I’ve never liked that saying much. The idea that a stranger could fall in love with your smile might sound romantic, but if you think about it, it also seems a bit creepy. And exhausting. “Smile all the time!! Just in case!”
Some better advice, I think, is to be yourself. Your normal, every day behavior might brighten someone else’s day: when you give someone a compliment, or wear your favorite t-shirt, or perform your usual song and dance routine from the driver’s seat when that one song starts playing on the radio.
You be you… because you never know who may appreciate you for the crazy, wonderful, hilarious person that you are.
