Terrible Tuesday

Today I read in the news about the man in China, who was previously a doctor, who killed eight primary school children with a ten-inch knife. He was apparently suffering from mental illnesses. When I hear of news stories like that, I really just don't know what to do. Was there even anything anyone could have done about it? So many lives, so many families lost, and all because they were in the wrong place at the wrong time. Why does there have to be a 'wrong' place or time in the first place?
Anyway, back to my own tiny little bubble, my sister and I now have violin/piano lessons on the same day, which means that both of us (since neither of us practice during the week) require to practice piano/violin in the short hour between school and the lesson. That doesn't work well - I basically went to my lesson without having practiced at all this week. I couldn't even blag it - I have so much stuff on my mind, I really find it difficult to concentrate. My sister, on the other hand, did very well.
