It's a wee bit dangerous to walk in and out of the house right now. I've already had icicles fall on my head once this winter and I'm not in any hurry to have a repeat experience!
However, the jagged icy daggers of death do have their uses.
For example, if one (*cough* the Professor) wants to travel to work in style, say, on a feisty blue unicorn, we can arrange that for you.
Tally ho! Can one say "Tally ho" whilst riding a unicorn? No? Oh... Only while hunting foxes. Right.
