ARDMORE, Pa. — Lindsey Vonn sat on a stone wall 20 yards from the first tee at the Merion Golf Club on Friday afternoon. Her boyfriend, Tiger Woods, had just teed off, striding down the fairway with thousands of fans in his wake.

Vonn went largely unnoticed.

“I can be normal by myself; no one notices me,” she said. “But wherever he’s around, we’re living in a fishbowl. I didn’t quite know what I was getting myself into. It’s weird. But it’s just something I have to deal with. He has his job, and I have mine. I just have to get used to it.”

One thing is bothering her.

“Some people seem to forget that I’m not just Tiger’s girlfriend,” Vonn said. “I’m actually a successful athlete. I’m Lindsey. I have my own career and my own life.”

It has been three months since Vonn and Woods announced that they were dating. On Friday, Vonn repeatedly said: “I’m very happy. Things are great.”
