"love it! love it! love it! you are brilliant. I think it's perfect!
I am so happy."
It's not that my ego needs vigorous stroking, it's just that it's nice to have someone say that you did a good job. It also makes up for the clients who are absolutely hideous.
I also like it when they realise that they might not know everything this is to know about my profession:
"... not sure if its possible and if not please tell me to get with the program..."
Some clients are just great.
