The war wages on:

Mike and Mary found Cockroach #2 in the kitchen tonight. They were not nearly as kind to #2 as I had been to #1.

When I found #1, I caught him and escorted him outdoors. I threw him off the balcony and he promptly ran back towards the building, possibly into one of the apartments on the lower level.

When Mary found #2, she screamed out to us. Mike bounded into the kitchen, caught the bugger, and in a nearly unparalleled display of manliness smashed #2 against the wall. He then yelped in pain because it hurt his hand.

Theoretically, I suppose #1 and #2 could have been one and the same. We'll see if any more show themselves.
