I turned down an assignment involving my girlfriend's son's 12U 50/70 rec team, because I didn't think it would be appropriate for me to work his games (we live together, if that matters). My assigner thinks it isn't an issue. I feel like it's a can of worms I'd rather not open. And I'd also prefer to be able to just watch the game if I'm available. Where do you draw the line on working games involving family members, friends, kids of friends, etc.?
