it's simply the best. you wanna leave? just go! don't say anything to anyone. do you have trouble with friends who love prolonged goodbyes or friends who try to convince you to stay longer? not anymore. you're already halfway home before anyone even realizes you're gone. "you should have said goodbye!" well, maybe i saw my opportunity to vamoose and took it! they should be saying, "you're a visionary, a true go-getter!" anyway, it's the most satisfying move to pull in any social situation and i recommend you do it whenever you can.
