May's birthday is coming . Shall we buy her a birthday present or let her choose one for herself ?   I think a surprise party may be better . But I forget when her birthday is .   You are such a good father . It's next Sunday .   Sorry . What shall we get for her ?   What about a cell phone ? She is old enough to have one .   Good idea . Shall we search on line to find an appropriate one or go to a phone store ?   Maybe we can try shopping on line .   Sure . Okay , here is the website .   I'm sure that May would love the pink one .   Probably . People's consumptive habit is changing rapidly because of the internet .   Totally . Computers bring with them convenience.Oh , what's wrong ?
