my SIL's family (my brother's wife) say grace before each meal - moreso for family dinners. I could say the grace by rote now, I've been hearing it since I was 4 1/2.

I've done a pagan grace once at a family dinner and everybody looked at me strangely - so I've stopped even offering.

I do say a private "thank you", but I also do do a lot of ritual chanting while cooking, I use cooking as ritual putting love and power into the food, this is basically kitchen witchery. Tonight's dinner has been a labour of love, I've been working on it all afternoon - with full-on ritual stuff happening in the kitchen (there is even a salt pentacle on the floor) - well it is beltane/samhain (sthn hemisphere/nrthn hemisphere).
