For a heartbeat, Jeremiah tilted his head in surprise towards the young man beside him. He didn't know what a barista was? Although he supposed that could just be that he didn't know the title. "I worked in a coffee shop," he explained, still a little surprised that he was explaining this. "I made coffee, and hot chocolate, tea, those sorts of things. Mostly coffee though - mostly espresso, and sometimes pour-overs." Not that he necessarily expected Wren to know the difference between those things, but it was where his brain went, technicalities of coffee.
"Milkshakes are cold, but maybe you should have a cocoa then - did you like the milkshake otherwise? The taste of it I mean? I think we could make you a vanilla cocoa, and it would be warm." He didn't have the milk though, and he suddenly wished that he did because he could make a really proper hot vanilla cocoa then, with milk, and chocolate syrup and a pump of the vanilla he kept on hand for when he felt like something sweet in his espresso. It wasn't often - but sometimes.
He nodded his head back towards his house, snapping his fingers at Heart, and letting Wren follow as well. He didn't know what to say about the worms, or the fact that the boy seemed to be eating them. "What else do you like to eat? I've got some fresh bread at my house," he added.
