[speaker001:] You mustn't touch the wet paint, Bill.
[speaker002:] I'm sorry. I won't do it again.
[speaker001:] Try to be more careful in future.
[speaker002:] I shall. I wasn't as careless as John Sampson. He walked across that wet cement over there.
[speaker001:] The workmen oughtn't to leave it without a no tice.
[speaker002:] The headmaster asked them not to do so.
[speaker001:] Then why isn't there a notice?
[speaker002:] They went to their stores to get one. Here they come with it now!
[speaker001:] But look at them! They've forgotten about the wet cement and they're walking across it to put up the notice!
