I'm beginning to think it's You

I was up all night,  
Working on a ton of files  
By 4-watt moonlight.  
Thought I’d only be a while  
With my paper purge,  
Didn’t think twice, so all right:  
In bed by midnight.  
But no way, ‘cos time will merge:  
When one thing clones two,  
Grows many from few,  
Gives answers to clue,  
Dyes rainbows their hue.  
Taught trees all they knew.  
Learns cats ways to mew,  
And cows how to chew,  
And doves when to coo.  
How dogs use the loo.  
Why we should eschew  
A bridge gone askew.  
But won’t join me to  
Walk miles in my shoe.  
Go cuckoo due to  
No sleep when it’s You  
Who’s blocking my view.  
In spite of the urge,  
I never can silence Your dirge.
