Down The Wrong Hole

It has been mega cold here, seeing as it's winter in the Southern Hemisphere and I've had my heat pump on high a lot which has given me a slight headache and made me mega thirsty, so I thought I'd better re-hydrate myself with a nice glass of cool water. I start taking refreshing gulps of it but before I know it, the water ends up going down the wrong hole and I end up in a mega coughing fit! It makes my eyes water and it's hard to stop but luckily I had the rest of my water on hand to help soothe my throat.
