Hilarious Bman. I too know what you're talking about. But I had a great experience the other day. My eight year old daughter was telling me that I had too many grills. My wife instantly chimed in, "But we love Daddy having grills. He cooks us all that great food. We don't want him to stop." I thought to myself with a small grin, "My evil plans are are working perfectly. The entire family is nearly assimilated. Bwah, ha, ha, ha." (That was an evil laugh, BTW)
In twenty years of marriage I've learned the secret to having hobbies and not being given too much grief over them. Make sure they produce something good! I have settled in to three hobbies: Woodworking - I've built most of the furniture in our home, deer hunting - my family goes nuts over the summer sausage I make, and Weber grilling - I'm a grilling rockstar in my own home.
If the the productive nature of my grilling ever starts to wane in my better half's eyes I just play the "at least I'm not..." card. You know, "Hey, I could be at the casino - strip club - bar - insert your vice here. At least when I'm tinkering with these grills you know where I am. I'll bet a lot of wive's wish that's all there husbands were doing!" Yes, it's a last ditch defense tactic but I'm not above going there when threatened.
Just keep making the goodies, make stuff for the in-laws, invite all your family friends over and feed them. A final tactic, and I don't recommend it because of how you would suffer, stop cooking for a while and let everyone see how much pressure your grilling takes off the family, and how much money you might save when you aren't going out.
