Here's a different angle for this though: My parents are both religious and are not pushy with me or my family so we don't tend to have too much conflict there. Still, whenever we come over (mainly if my wife isn't there) and eat, my parents pray before eating and as was tradition growing up, hold hands while doing it. I've no problem sitting back and waiting for them to finish out of respect, but they have taken to reaching out and grasping my and the children's hands while doing it.
I'm positive they are not trying to convert us surreptitiously and that it's probably more habit than statement, but I cannot help but feel awkward when they do it, like it's a symbol for them that there's still "hope" for me and the kids or something. I've no desire to make a big deal out of it, but I just find it odd. What would you all do?
