IMHO, I like a little anger, it means the person cares. Like a high jumper missing, but clapping to the audience. Shouldn't he or she desire to make the jump enough that he/she can be a bit angry with the universe, or themselves? Why celebrate a miss?
All the hugging is fine, I guess, whats done is done. But in the NBA, miss a free throw, high five everyone. What? Odd, really. It's nice that teammates want to support the athlete, but the person doing the missing perhaps shouldn't be celebrating a miss. I suppose it could be construed as seeking support.....
....back to Mu. Perhaps she will stew and take it out in the race and run a gold medal, all-time best for herself.
