If I said to most of the people who auditioned, 'Good job, awesome, well done,' it would have made me actually look and feel ridiculous. It's quite obvious most of the people who turned up for this audition were hopeless. ↗
I suppose if you've never bitten your nails, there isn't any way to explain the habit. It's not enjoyable, really, but there is a certain satisfaction - pride in a job well done. ↗
