"Well of course you kill things with that sort of attitude. You should stop thinking like a murderer and try instead. It gives you much nicer results than thinking all killer like." Really, the more he spoke, the more convinced she became that he definitely needed happiness, and lots of it. Next time, she'd bring brownies.
"Doesn't that look nice?" She gestured to the plant with a big smile on her face. Surely he'd think it was just as wonderful as she did.
