The anti virus Norton system I had been using expired, and I did not renew it.  Now the AOL and YAHOO email accounts are loaded with unwanted messages.  I am using Gmail to send emails, as I believe it is impervious to spam.  Class work at the university suffered a serious blow when I could not find an UNDO button on MS WORD ( there is no toolbar to see! ) and so I lost an entire assignment by mistake and could not retrieve it. I did find two clean pages from a proof, which I stapled and turned in! Now there is a little quiz online to do before Friday. Classwork on Friday will suffer:  I have a ticket to the symphony to hear the new conductor, Louis Landgree.  Yesterday's Wagner Society meeting, devoted to the Flying Dutchman, was a pleasure.
