hi,
Does 'we are running late' means 'we are always become late' or sth like 'we are again late'?
thanks :roll:

Hi Sevide,

We are running late means we have lost some time and now we are behind in what we should be doing. You can use this for transport when a train has been delayed by a certain period of time, say 20 minutes and you would be told that the train is running 20 minutes late.
