the hardest thing is not having a pat answer for those difficult questions. When you think about it, theists really wouldn't have to answer questions with real fact unless they wanted to take the time and find the fact. They can always say, "That's just how God made it." or "Because, that's how god wants it." or some variation of that answer.In other words, Atheists tell their children the truth. They don't use "because it's God's will" to pacify children with a quick answer.
Personally, the hardest thing for me is sitting through "Come Lord Jesus, be our guest, and let these gifts to us be blessed." every night before dinner. I'd prefer to drink a simple toast.
Hmmm... Maybe I'll say something like, "Thank you all for coming and I wish each of you health and happiness. Please, enjoy the meal. Let's eat!"
