Freezing

There's no heat again at the Institute. I'm freezing. I meant to type a short email to my friend Jane and ended up writing a mini-novel just to keep myself warm. Until I realised that it hurt to type.

Someone brought a heater into the office, but it has the weirdest plug I have ever seen. It's got five prongs. Two on top, two on the bottom and a flat one in the middle.

Is that legal?
