I know how you feel: back in 2001, my son left for college on September 13, 2 days after the plane crashes in New York and Washington.  Life went on, but our need for connection and caring was sharply defined.
I am horrified by the rash of suicide/murders that have occurred over the past year.  There were the shootings at the Amish school in Pennsylvania; then the terrible events that happened barely two months ago at Trolley Square, right here in Salt Lake City.  Now, we hear about Virginia Tech.  I know we cannot live our everyday lives in fear of the occasional lunatic with a gun.  However, we cannot allow ourselves to become complacent either. 
The repeated examples of killings, and suicide, both in the USA and in Iraq, are disturbing indeed.
