As a bit of a gardener myself I appreciate the analogy.
One thing I think I'll take care of FOR Jethro is this, tell me if I'm wrong Dude:
What J does before these "spurts" of his W's, is become so dispondent with her growing apathy that he REMINDS her that she needs to be working on the M. Right, J?
So it's not like he's just doing some day to day stuff differently that brings on these improvements. Now, that WOULD be frustrating, no?
Short term memory problems, can't remember what else I was gonna post!
