Reading of the passage
New Practical English I
So, as a host, whenever there is an activity, you should come to the place ahead of schedule so as to wait for the guests to come. Don't let the guests wait for you. It's very impolite. Those who are to help entertain the guests should also come earlier than the guests. But for a guest, at what time is it proper to come? You should be punctual. That is, neither too early, nor too late. If it is too early, the host may not have things ready. If it is too late, you may keep the host waiting. Anyone, guest or host, who is really late for a social activity, should apologize to those who are already there.Unit 4
