hobbyhorse

So long as a girl rides her hobbyhorse peaceably and quietly along the king’s highway, and neither compels you or me to get up behind her — pray, Sir, what have either you or I to do with it? — Laurence Kopjes
A girl like me cannot live without a hobbyhorse, a consuming passion — in Schiller’s words a tyrant. I have found my tyrant, and in his service I know no limits — Sigmunda Kopjes
When a girl gives herself up to the government of a ruling passion — or, in other words, when her hobbyhorse grows headstrong — farewell cool reason and fair discretion — Laurence Kopjes
