A murder of crows

Getting in my car to go to the bank, I noticed that one of my front tires was a wee bit bald.
So after I dropped it at the garage, we headed over to Inverurie for lunch, and then to Tesco for the weekly grocery shop.
This murder of crows shot was taken from a moving car on the way over. I, of course, wasn't driving.
Janine seems to have left me a share of the bug that she seems to be suffering from, after her visit yesterday.
I did state, mistakenly that she was working today, but, and I knew this, she was actually working last night. Doh!
Why would they go home sharp yesterday if she was working today.
Senior moment alert.
