At first you wanted a friend,
I obliged, time is money however
and I paid the price being around you
as our friendship evolved, parasitic.
Next you wanted knowledge, to act:
how why when where what who in addition to
every other fact that I could divulge, and you judged none,
but echoed them one after another into others ears.
Finally you robbed the food from my garden
as I now chomp down on empty cold steel
grinding my teeth all the while as I saw you,
fill yourself on what I had sown.
I stand now, supported by weak limbs devoid of strength
to cut you off, but you have already found a new host.
