Hi,
I am mixed up with the expression must have looked...Would you please explain what does it mean and when do we use it,give me more example please,(you
"When I was walking from the train I think every man on the street must have looked at my chest, it just makes me sick.
It expresses, about a past event, speculation that is very close to certainty.
eg He fell down the stairs so badly that he must have broken his leg.
eg He's so late that I think he must have had a car accident.
Best wishes, Clive
