So we r in the car on way to holiday. Kids initially excited, then DS age 7 says "I'm bored". Daddy said, ok let's play a game, who can spot the red car first. We have played this before and every time it ends in tears as both DS 6 and DS 3 like to win, but there can only be one person to spot the car first.
Anyway, heart sank. But I didn't know what to do - couldn't suddenly intervene and stop the game as that would b tears. Also didn't want to undermine DH.
Anyway - as predicted lots of angry words and tears and 'no he didn't see it first I did' etc... so I said, 'ok no more game, it always ends like this and we're not playing anymore until the day you kids can play it without crying and causing a fuss'.
I indicated to DH the harmony turned to chaos was his fault for suggesting the game. I know that was wrong of me and I feel bad for blaming him. He meant well. So yes AIBU for that! 
Anyway, just wondering, after DH announced the game, knowing how it would end - is there anything that I could have done to prevent the inevitable ending??? And keep DH, and two DS's happy???
(just asking because there WILL b a next time as DH often does this sort of thing - he's a lovely DH by the way, just no memory of how his games tend to end)
(By the way, all happy now with tablets on and headphones in! And we r nearly where we r going!!!)
