I have a small dark side myself and sense of humor 'sometimes' . I think we all do . Now at first I would have said kill the caterpillar but nowadays ............ ... I'm trying to be more understanding so I would suggest that you nicely take him off and toss him in the bushes outside or something . That's what I do nowadays , however it's not quite what I did to one that had eaten my newest rose bud before it could open . So when do we get to see these new happenings ?
