It is almost the end of the work week.
I still have a few conference calls before winding down for the weekend. As far as I can remember, this has been one of the most challenging weeks ever.
I think about this last sentence, and I believe it is wrong.
This has not been a tough week; **I am** unable to get over a tough week.
A sad realization before a weekend.
I guess I need to rest a bit.
