When you realise you've overdone it ...
For heaven's sake! I've been to work, eaten at home, been to a Gaelic evening class, and done a spot of tidying up. Put some laundry in, hung a few pictures ... but really nothing unusual.
I've done no research, no writing, no paperwork whatsoever. But I'm knackered. What kind of a wimp am I? It's 23:17 and I have a little dusting to do - just the stuff on the upstairs landing. And then will I feel like opening a book? Questionable!
I'm not doing too much, I'm only a day older than I was yesterday ... ah, that's it:- Time is flying by quicker. Of course.
