"Why the long face?"
"You seem bummed. Wanna go do something fun?"
"Don't lie to me. What's wrong?"
"If you don't want to talk about it, you don't have to."
"I'm not making you uncomfortable, am I?"
"You've been awfully quiet today."
"You know, you're not really acting like yourself."
"There has to be something I can do to turn that frown upside down."
"Want to talk about it?"
"It'll be okay. Everyone has bad days."
"Oh, come on! I can't leave you all alone over here, mopey and unhappy."
"Let's see a smile!"
"You're so much prettier when you smile."
"You know, if you want to just relax and take the day off, I don't think anyone would blame you."
"I know you've been feeling a little down, so I brought your favorite snack and a movie!"
"We could just cuddle or something, if you think that would make you feel better."
