How do you like skiing , Pat ?   I love it . All my life I wanted to learn to ski . Finally I took lessons last year .   I suppose skiing is easy for you .   No , quite the opposite . I thought I'd never stop falling down . Then all of a sudden I started skiing much better .   I see . Do you ski often ?   Every chance I get . On weekends I ski all day long . Sometimes I even ski at night .   That sounds great .   Oh , yes . The ski slopes are well lit . It's really nice to ski at night . Why don't you learn to ski ?
