I don't understand why everyone seems to be unable to eat nowadays without posting a picture of their food on the internet first. Congratufuckinglations; you have access to food just like the rest of the first world.

this is my generation.

Your Dad should consider anger management, because clearly the supposed "lord" ain't helping him. Also your daughter needs to learn selfie control.

I personally think the two highest compliments someone can give my cooking are taking pictures of the finished product the destroying everything that's on the table. It's kind of like a thumbs up or +1 or like or what have you for food. I take pictures of food and post them to mybook and facespace and myface and spacebook, but that tends to be when I go to the really expensive restaurants about once a year that I do business with, or when I'm particularly proud of something that I have personally made. Examples would be the first time I ever made sushi and sashimi as well as the first time I ever got a soufflé to work. That said, some people take it to excess. (Yes. I know it's myspace and facebook. This line is to keep people from correcting me)

I take it she got no dessert and was sent to be early with a good old fashioned attitude adjustment prior.

Your daughter was rude. For heaven's sake, take away her phone when she's at the dinner table. Set some limits!

It sounds like both parties were being disrespectful. Op's daughter for using her phone during prayer and family time and op's father for flying into such a degenerate rage as a GUEST in someones home. In my opinion what we have is a multigenerational parenting fail

YDI for raising such a dipshit of a kid. No phones at the dinner table should be pretty standard.

Pshhh, my family is religious, but we don't pray at dinner time. Heck, I don't even believe in god ( that's my choice ) and they still go ape shit when I refuse to pray or disagree with them on religion discussion. Sorry, at any age we shouldn't force anyone to pray if they don't too no matter if the grandfather or any relative is extremely religious come to visit. Religion is a personal choice, but phone at the table is a bit rude and I am guilty of doing that.

Not your fault OP that your daughter's rude (should've waited til grace was over til she took her food pics) and your father's a nut.
