If you come to my office and the door is open, but I'm not there, chances are I'm helping students out in B107 or B162 - just listen for the dulcet tones of my voice. If you still can't find me, you can ask anyone in the office whether they've seen me or not.
If you come by my office and the door isn't open, please slip a note under my door to let me know you were there - I hope to make this a rare occurrence, but things *do* get a bit wild sometimes, and I might be a little late getting back to my office.
