My friend's dd has just got a prominent role in her ballet production because the other girl has injured her collar bone. Her mum feels incredibly guilty as she knows the other girl's mum was so proud of her daughter getting the role but at the same time she's thrilled for her own daughter. I don't think she should feel guilty - there will be other opportunities for the other girl and sometimes fate just deals out the cards that way doesn't it? Surely every job or opportunity we get - someone else has lost out?!
