We knew McKayla Maroney was done, but now it's official. Except that she doesn't want to use the word "retire". Gymcastic did an interview with her (requested by McKayla herself) and it's amazing, just watch it. It tells you pretty much anything and everything you need to know about McKayla.
My first impression was that she can't stop talking. There's no need for interviewer, you can just point the camera at her and she'll do the rest. It's both endearing and annoying, and it gives off the impression of a little child. It's like her mind is running 100 miles per hour, she's self obsessed with her thoughts and she's so excited about her discoveries about life and just wants to share everything she's thinking and has limited time to do so. I'm guessing it's just her personality, but there's probably some nerves involved too. Oh, and the fact that for a long time she wasn't allowed to say anything, she just had to hold everything in. As she tells in the interview, talking to other contestants was discouraged (to put it mildly), and as for the media, just keep smiling (no matter with how many broken bones). So now she says it all.
