What the hell is going on in this world???

Today a NASA contractor shot a NASA employee and then killed himself. This happened at Johnson Space Center in Houston which just happens to be where my sister, Patty works. As soon as I heard the news I was burning up the phone lines and trying to call her desk, her cell, her home numbers - but no answer. Then I called my parents in San Antonio to see if they had heard from her, but they hadn't. So my Dad got on the job of trying to find out what was going on.
My mom called back to say that Patty did call Dad back to let him know she was okay. That she was on 'lock-down' and couldn't leave yet. She works in the building right next to the 44 lab - which is where the incident took place. When they were allowed to leave, she FINALLY called me back directly.
I tell you, THAT was hard. I mean, it certainly doesn't compare to what happened at VT, but when it's close to a family member, oh my God, it's hard.
I just thank God she wasn't in that building and I am so grateful. I tell you this whole week has been so weird. I think I've told everyone that I love them (esp Mike) about a thousand times since it proves that you just never know.
In other news, I am heading to San Diego on Sunday evening for a trade show next week. It ought to be a good time. (Boy do I need THAT.) I'm tired of worrying and crying.
