Hmm, before I decide to "invest" any hours, could you tell me what the rate of return is?
Probably not as high of a return as going to your daughter's fastpitch tournament, hanging in the pool with your son, taking the convertible Stang out for a scenic drive around a lake in the mountains, going fishing, lounging in a hammock with a Painkiller nearby and a sleeping cat laying on you, playing with your dog, cooking a hellacious meal on the grill, etc etc etc.
I love my dog. After spending the afternoon playing keep away (he doesn't understand catch) with him and both of us salivating at the grill's wonders, we go inside, I start playing video games, and my dog lays on the bed with his head on my lap and watches. I know he watches because he barks when I capture the flag.
