Whoever heard of someone 'planning' to take up smoking?
I mean, you either go out today and buy a packet and light one up, or you don't. You don't draw up a plan and mark the day down on your calendar to start...that's just silly.
"That's it, I've decided on the 25 of November at 3:17pm I'm going to take up smoking!"
Don't mind me...just taking the piss, which is aussie slang for teasing.
