Rang work to see what was happening, they said "nothing, I wouldn't bother coming in".
Ok then, I won't! Hurrah!
Bonus for Toby who had an extra long walk in the snow as a result. Had a (one-sided) snowball fight with him, then he frolicked about with all the other mutts. Back home, cup of hot chocolate, thawed out. Heaven.
Now I just need to find an excuse not to go to the gym, and I'm sorted.
