It wasn't the first time that Neville had been sought out for plant advice. If there was one thing in the entirety of the universe that he was good at besides clumsiness, it was plant related things. Hearing his name wasn't a surprise. Seeing the person attached to the voice which had called his name, though, was a bit more unusual.
"Andrew," he greeted, a little smile on his face because the man had always been friendly enough to him. Neville had no reason to be rude to him or to anyone else. "No, not at all. Can I help you with something?" It was a stupid question, really. He knew that Andrew likely wanted some sort of advice or something to have come all the way into the store searching for him, but there was the question all the same.
