Bluesday

Yesterday was Monday
We called it Funday
But I hate Tuesday
So I call it Bluesday
Weathermen warn
It'll rain all morn
Machines are bust
So I've had to de-rust
Thing I like most
Ability to post
Is hampered today
Bigwigs at play
I've hid in the loo
To write this to you
So with rain coming down
Shades of blue all around
Not too much time
To jot down a rhyme
Roll on day's end
I tell you, my friend...
