One french commentator always asked the same question about her game, during her matches "WHY doesn't she come to the net more often, why ?" , trust me this sentence is kinda part of my childhood
We had much the same thing here in the U.S. Bud Collins was always saying she should go to net more. It became a kind of recurring joke between Steffi and him.
Bud: Are you planning on going to the net a little more?
Steffi: No, but I'll go in a few times -- just for you. [And she smiles coquettishly at him.]
Bud: Was that *you* I saw going to the net so much?
Steffi: Yeah. Actually I was thinking about you during the match.
Bud: You played serve and volley!
Steffi: Yeah, but I made a few mistakes on it, too, I have to admit. So, uh, some good ones, some bad ones.
