Classes Cancelled Monday and Tuesday

Guys,

I have an emergency to deal with so I cannot hold classes on Monday or Tuesday.  You should have received an email already from the faculty secretaries’ office saying so, but I just wanted to be clear.  Everything should be back to normal, or as normal as it can all be, by Wednesday.
