A 3-foot putt can be more nerve-racking than a 9-foot putt because a 3-foot putt you should be getting in. A 9-footer, there's a chance it won't go in.

Two weeks ago at the U.S. Amateur, my mom caddied, and that is kind of a different feeling, because she's your mom and you have to listen to her. It was really comfortable having my mom there, but it's also really relieving and comfortable to have someone that knows the course off their hat, really.
