Kidism

I was helping Kamae practice piano and she was getting really frustrated and almost started crying. I told her to stop playing, calm down and explain to me what she's not understanding so I could help her. She put her arm across the piano keys, laid her head down on her arm let out a huge sigh. I asked her again, "Kamae, you have to tell me what you don't get so that I can help you." She lifted up her head and loudly said, "F 'n G!" I just bust up laughing, but of course, I couldn't explain to her why!
