How we change what others think, feel, believe and do
Out of time
Say that you are busy and have other things you must do.
Show your concern for time by looking at your watch (they may get the hint and close the conversation for you).
You can also hint ahead by telling the other person at the start of the conversation that you only have a little time.
It also can help to give the other person a reason why you have only a limited amount of time.
I can only spend a couple of minutes on this as I need to catch Jim before he goes.
Sorry, I have to go to catch a train.
Goodness, is that the time! I promised my husband I'd be home before six.
Will this be quick? I've a meeting at ten.
In many situations, particularly ones involving work and family, our calendars are pre-populated with meetings, actions and events. This gives a perfect excuse for many situations.
At other time, perhaps at parties and places where you are not going to actually leave, then this excuse is less effective.
