He approached the table, feeling his spirits lift with each step. He bought Mr. Buttons, and then proceeded to buy a coffee, and a slice of cake.

He felt an urge to just wander, to do nothing and savor the moment. His mood lifted, his worries melted away. He'd find a bench somewhere and simply sit, Mr. Buttons nestled in his lap.
