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