So cold, that the lip balm that I had applied right before I left the house froze on my lips.
I did not discover this until I went to open the glass doors into my building and saw my reflection.
My lips were a shocking opaque white.
I rubbed most of it off (I had been quite liberal in my application) and luckily by the time I made it up two flights of stairs, the rest had melted, and I was a normal colour again.
Now, there have been colder mornings than this in the past month, so I wonder how many times this has happened. I am a little scared now.
No wonder the guy I met on the footbridge jumped a bit this morning!
