@ossobuco,
I put some thought into the right tone to adopt for this losing post.
Gallant loser? Couldn't be happier etc etc. Great woman, yada yada.
Casual indifference? Ah well, only a game; sense of perspective blah blah blah.
It's hard to remain objective when you're aware that certain participants have been free with their favours (yanks: note correct sp.) with various match officials.
Yep, I've settled on
whinging bitterness.
