  • Huh? So by not killing the roaches, he was prolonging their stint as a roach?

  • My mother used to date a Buddhist--she'd often complain about how he'd capture the roaches in his kitchen and bring them outside (instead of killing them). She used to laugh about coming back as a tick or a roach because she'd spent so many happy hours devising ways to kill them. Later I had a friend who was studying to be a yoga teacher--she told me one of the things they heard in their training was that teachers who make wrong actions are probably reincarnated as roaches. I think the idea was that killing roaches somehow helps them make their way out of darkness and back toward enlightenment.

  • I saw a roach on my stove tonight, so I grabbed what I thought was a can of Raid. It turns out that Resolve also comes in red cans. So, I was chasing this roach around thinking, "DIE, ROACH, DIE", and it wouldn't die. So I finally killed it by sheer blunt force, but I doused our stove in carpet cleaner in the process. Bad day to be that roach.

  • When meaning roach fish is the plural also roach?

  • I felt better when everything was in
    it will take me some months to get back to normal:
    I can't even find a roach to commune with.
    I have lost my rythm.
    I can't sleep.
    I can't eat.
    I have been robbed of
    my filth.
