I took a few months' break but did check in to read the forums and game updates, however occasionally. Eventually something caught my attention and I logged back in to the game. I've enjoyed the Distraction and Diversion games - Evil Trees, Shooting Stars, Penguin hunting. These are fun as opposed to grinding, in my opinion, and give you a chance to interact with (mostly) nice players while you do them. Absolutely nothing wrong with taking a break, I even recommend it :D
