It's our duty as human beings to resist going back to the office as much as possible. To gain back some of the life we otherwise would spend on commute. Work is for work, not for socializing, or having fun, or playing Xbox and table tennis. I mean, sure, these are nice perks, but we are being paid for the work we do, not for the fun we have. And working without being distracted by some colleagues loud music in the headphones, or the chit chat of others, or the "sorry, quick question" of some manager, improves my quality of work tremendously.
