lovable curmudgeon 

An often disagreeable young man with a serious disposition. Does not tell nor receive jokes well. However, he is kind and generally likeable. One might say his name is Andrew

Andrew just complained about washing all of Mason's dishes again. He did a great job cleaning and putting them away yet still had something to say about it. What a lovable curmudgeon.
