"I just saw the cutest golden retriever puppy, and I totally auto-smiled all the way home!"

"I saw that cute guy/girl at the coffee shop and I don't know what it is about him/her, but I auto-smile when I see him/her."

"I know I've only been seeing him/her for a month, but I auto-smile every time I see a text from him/her."
