Every now and again, a situation will make Us Rhinos feel lonely, or displaced. There is a sense of foreboding, disquiet about the future.
Rhinos do not actually play the harmonica, but there is something about the sound that Rhinos like. Good for pensive days.
Fortunately for Us, We can do a good imitation of a harmonica by gargling and keening at the same time. Or good enough for Us, at any rate.
