Talking of which, my sister found out over Christmas that my 15 year-old nephew and godson smokes weed and absolutely lost her shït about it. The fact it was obvious seems to have passed her by. Anyway, she keeps catching him at it/finding his stash and losing her rag - which is all very funny. So now he's supposedly said he's stopped smoking.
However, the other day on Facebook, she posted a picture of a load of demolished pizza, crisps, biscuits, etc that he and a mate had polished off in the front room and not tidied up with the words 'A little late-night snack-ette left by my son and his friend' and appeared not to put two and two together.
I didn't have the heart to tell her. I'm slightly alarmed that a sister of mine is that naive, tbh.
