458.6 actions and situations that have just stopped
We also use the present perfect progressive for actions and situations which have just stopped, but which have present results.
You look hot. ~ Yes, I've been running.
Sorry I'm late. Have you been waiting long?
I must just go and wash. I've been gardening.
