I'm off to the store now, do you need anything?
The train is off, so we'll have to take a bus
The milk has gone off, it smells terrible
He's off sick today with a bad cold
We're off to the beach for the weekend
The alarm clock is off, so I overslept
The lights are off in the living room
She's off caffeine for a month to see if it helps her sleep
The game is off due to the rain
The boss is off duty today, so someone else is in charge
I must be off now, it is getting late.
Alright, I will see you tomorrow then.
Yes, have a good evening, goodbye!
It's getting late, I should be off now
It's getting late, I should leave now
It's getting late, I must go now
