history: I can't believe I didn't listen to my child when they told me that someone is picking on them. I feel terrible now he doesn't want to go to school any more. I feel terrible about not listening to my child's complaints about being picked on. What was I thinking?
current: Sorry to hear that.  How old is he / she
next: He is 13 and now he doesn't want to go to school any more. Bullying is such a terrible thing. I now listen to everything he tells me.
