Aren't there any signs of depression in plants? I'm sure we could find a webpage on it somewhere on this World Wide Web... I mean it would seem like plants with half-eate..oops I mean droopy leaves would just need some counseling. And if they're really quiet, keep to themselves alot. You know, any changes in their normal routine and behavior. Who knows? Just be satisfied that the recently deceased plant did not get a hold of a gun and go postal on the other plants. That would have been a nightmare....That is why I firmly believe in keeping the gun laws strict and keeping guns out of the hands of plants!!! You never know with them...
