Last night no one was hating her (except for the odd few who were rightly deleted).
Last night people were making realistic observations about what they heard and saw.
Last night the pressure didn't get to her.
Last night she, encouraged by her mother, pretended to have stage fright to counter allegations in the press that she was becoming bigheaded.
Then she goes on to give an above average performance tonight & everyone is blown away in comparison.
If she had just given a decent performance in the first place last night there would have been no emotional story.
People have been had, but that's OK if they're happy.
