slight shocking sour

I'm starting to detect it now
a distinct note of sourness.
Pungent, sharp and deep of tang,
growing on the palate as we go,

as we find out
I have become

slightly sour,
without noticing.

Suddenly I tried
to speak, to see, to say
- I always have so easily, so
readily. So clear

and sweet.
This sourness entirely
shocks. The last thing I
expected is to feel, or
taste, or

be.

Like this.
I thought I'd tend
to bitterness.
