Q: What Constitutes a Friendly Game?

I played a 1500 pt WHFB game this weekend that raised some questions for me.  My Ogre Kingdoms opponent asked me, "Is this a friendly game?"  I answered that it was, and that it was my first game against Ogres.  He responded by telling me that I would definitely want to use my power dice to dispell his toothcracker (or some other unpleasant sounding) remains-in-play spell.  I did so.

As the game progressed someone on the sidelines did a bit of kibitzing, reminding me of rules or things I had forgotten to do, like re-roll for hatred, etc.  As things started to go south for the Ogres I could hear my opponent muttering "I thought this was supposed to be a friendly game" or similar under his breath multiple times.  Clearly he thought someone helping me remember things was beyond that scope, even though I am a very occasional player (1-2 times a year.)

So this raised the question:  What constitutes a friendly/casual game?

Thinking it over a little, I think these are the sorts of things I would do in a casual game:

• Allow my opponent to do something he had forgotten in a prior phase as long as it wouldn't rewrite history too much.  A good example is allowing him to rally a fleeing unit after charges are declared.
  
• Let any charges / range checks of my opponent that are so close as to be questionable go in favor of my opponent.
• I would not require explicitly visible actions (for people who roll so fast that you can't see anything and all they say is "okay, 4 wounds" during combat.)
• Be congenial over any rules that are  broken, but try and point out any obvious errors and give him the opportunity to correct them.
  
• Allow him to look up any rule that gets questioned without making disparaging comments about knowing the rules or the time rule lookups take.
  

Little things like this keep the narrative of the battle alive with a minimum of the sort arguing that takes the focus off the models and puts it on the cantankerous gamers.

So what are your thoughts?
