Bzzzzzz

Working away on the computer today, I a tiny movement out of the corner of my eye.
On my windowsill I have several mugs with pens, pencils, brushes etc.
A tiny black parasitic wasp (I assume, I'm no entomologist) about 5mm long, carrying something bulky, disappeared into one of the caps I put over some of my steel nibs to protect them, and me from getting accidental tattoos.
I tapped the pen holder and the bug flew out of the open window. Curious I lifted the lid to expose the nib to find about a dozen stunned aphids stuffed into the hollow at the base of the crowquill sized nib - food, I assume for the wasp's babies.
Some of the aphids were black and bloated, so I guess they were the ones with the eggs already inside.
Now, I'm an easy going guy, but I can't tolerate wasps nesting inside my tools, so I tipped the stunned aphids out of the window and their inevitable doom.
Am I a bad person? I think I can live with myself.
