Is that a big deal? Everyone has a private life that they need to attend to. It always takes priority over forum activity, so people should stop stressing out when managers are absent for a few days.
Rest is crucial to our mental health and wellbeing without which one won't be able to function optimally. It is okay to take breaks from the forum. I recommend it for anyone/managers who can. Returning, you will feel refreshed with a lot of mental clarity. It is no biggie.
