To keep from letting things get boring, teachers as well as students can benefit from all the classes that are being offered.  My philosophy is that you can never stop learning as long as you continue to wish to do so.  So, if you don't have a class or other obligations, feel free to drop by another teacher's area as you wish.  Otherwise a staff lounge or the dining hall are open as the need arises.  Also, as long as you don't get yourselves confused, you can be in two areas at once as previously stated before.
