She should rather be glad nobody forced her to play that darn instrument against her will year after year after year... When my parents bought a small violin for my 4th birthday, they probably hoped my face would be as ecstatic as Sophie's as soon as I held it in my hands. The exact opposite was the case. I wasn't at all enamoured with this screechy thing (you probably know or can image
what a small children's violin sounds like when played by a beginner), and did my best to avoid having to practice it to the point of mechanical sabotage. But my parents weren't the ones to be discouraged quickly and kept pestering me for years.
So, Sophie, enjoy your violin but don't force others to play one. BTW you're holding it wrong, the left thumb goes under the intrument's neck, and the way you grip the bow needs some work too...
