Now try this on for size:
I chucked a sickie yesterday arvo, because I just couldn’t be buggered leaving the house. I was mucking around on my mobile, when one of my mates messaged me, asking if I was up for a Maccas run. I told him to get takeaway and get me some nuggies, and he said he’d be round in 20ish. When he got to my place, he was whinging that the chips had gone cold, but I just got the chockie ice cream out of the freezer and dipped one in – absolutely bonzer! My mate looked grossed out, but I said, “Hey, don’t knock it ‘til you try it.”
