Days In Office

I come to office on a Monday
Leave every Friday
(Sometimes they call me on Saturday too)
Just Sunday is mine
Which I spend in anticipation of Monday

I've been told,
(By experts)
That there are other days
Like Tuesday, Wednesday and Thursday
But I refuse to believe them
Unless they show me empirical evidence
With excel sheets and progress reports
And graphs made into pie charts
Which I will pretend to understand

Still I wonder where do Tuesday, Wednesday and Thursday go.
In the boss' ass perhaps
