But going off Billi comment about prayer before a meal, I think it’s a good thing. A moment to stop and reflect, be grateful for what we have and appreciate the help and efforts of others. Sure most are a “thank god”, but even as an atheist when I’m with someone who says a grace before a meal I do stop and for just a few seconds appreciate life.
They may be thanking their god, but hopefully they remember that this is via other people and that they are in their thoughts.
