"How about 'yes'!" Gai declared with a stomp of his foot. Ooo Kakashi, do not make him go up there and force you out of that tree! "It would not hurt you to say yes more often to social engagements! If you are not more sociable, I will ask Obito to not issue you any missions! Then you will have to find time for me!"

That wouldn't entirely work--Obito needed Kakashi for missions, after all--but it was still worth making the threat to see if it could work as a bluff. Kakashi did seem to prefer escaping into his missions rather than facing time with his friends and comrades.

"...Perhaps the Hokage would even be willing to put a ban on Icha Icha novels!"
