All her. However, if you have to warn your kids to not set grandpa off, then you should either not have him around or not have kids. Because of that YDI.

That is when you take away the phone or instagram everything she does at all times of day to get her back.

Well, YDI for inviting your father over, she deserved it for using instagram, and your father deserved it for being a total douche.

FYL for having a daughter who thinks instagraming your food is cool

What a disrespectful person she is. Whether or not you believe, it is kind of you to respect the beliefs of others. Using a phone during dinner, behaving in such a disrespectful manner deserves a good punishment. Shame where our morals went, and shame that some of you here support such behavior. My assumption is that most of you are still kids, rebelling against parents, and do not understand morality and norms that are to be respected around elders abd family members. Sad.

Hypocrite!! Anyone who goes apeshit over petty transgressions is not sincerely practicing any real religion. Your dad is a fraud. He's a rageaholic that uses religion as an excuse, instead of obeying its teachings to restrain his temper.

First of all, your daughter needs to be more mindful of family time. That was beyond rude and inconsiderate. That said, why would you let your father in the house knowing that ANYTHING will set him off??? Do you REALLY want to live like that???

Sorry but it all goes back to the parenting.

Damn, she did sort of ask for it. I'm just sorry that you had to put up with it.

She shouldn't have done it, but your dad needs to realize that going "apeshit" is counterproductive. He's an adult and he should act like it.
