Alex has only had a smartphone for six months or so, and she's still amazed by how many smiley faces there are. As soon as he suggests texting him, she picks one out and sends it to him. "There. Two sounds great."

After giving him one more small smile, she turns to leave, but once again quickly turns back. "You might want to invest in a fire extinguisher. I don't want to burn down the building." With that, she heads for the registers again.
