I haven't become an American! Having a house in LA is just where the house is. It's just a convenience thing living there. I carry Wales around inside me. I'd consider moving back there one day. I never really left.
My serve and my forehand I pretty much always had, but my backhand was a made backhand. I worked on it for years.
My dad was born in Chicago in 1908... his parents came from Russia. They settled in Chicago, where they lived in a little tiny grocery store with eight or nine children - in the backroom all together - and my grandmother got the idea to go into the movie business.
