Brian and Christina were mentioning that maybe it would be fun to go on vacation together this year , John .  I thought that I already told you that I am going with Mark to Alaska .  Are you kidding me ?  You know what ? You and I had no plans , so I made plans with Mark . What's the problem ?  We have been together for a year and usually , people who've been together a year , take their vacation together .  I don't think that I ever heard of that rule before . Any more rules that you would like to tell me about ?  Go on your vacation with Mark and when you come back , why don't you just move in with him as well !  I am really looking forward to getting away from you . Far away from you ! 
Output:
No
