Chris has been having an irritating cough for weeks but totally ignores my MIL and my advice to avoid cold drinks.
Last night during dinner at my MIL's, I stepped into the kitchen to get more soup and heard someone opening the fridge door behind me...
so I said in a very stern voice: 不可以喝冷水!! (you're not allowed to take cold drinks!)
a voice replied: 我可以 (I can)
It was my father-in-law's voice
