Whatchacallit II

In reading last month’s ditty, I
Have realized of late,
That what I vainly preached about
Has been my own true fate.
My whatchacallit’s truly gone!
I’m in a brand new zone!
I don’t remember anything,
And, boy, how I have grown!
Or shrunk, I guess! At any rate,
I’ve had to start anew and
Invent a past and present that
More fairly is my due.
A myth, in fact, a naked lie,
A fabricated rout!
Complete with names and places that
I’ve only dreamed about!
But, wait, this seems familiar. Could
I simply have forgot?
I’ll never really know because
My whatchacallit’s shot!
