Lamb. Rabbit with a sad image

I think each of us knows people who are always sad. Nothing and no one pleases them. Next to such a person I want to take a shovel and dig myself. With an apology that I allow myself to feel happy. But there are animals, looking at which you involuntarily feel guilty. Unlike people, they do this not on purpose. Here, for example, a rabbit Lamb. Looking at him, you will never think that this is a cheerful and active animal, very affectionate and one that likes to eat well. Probably the whole thing is in the ears ... Hanging ears make him look sad.
