Satellite crash: How rational is my fear?

I keep reading that an old American spy satellite is going to crash to Earth soon.

Unlike a lot of the stuff the media have told me over the years I’m supposed to be afraid of (radon, Y2K, apples with razor blades, strangers offering me rides to the hospital to see my injured parents, tuna, Jamaican drug posses, anti-depressants, iced tea, Ice-T, cell phones, stuffed koala bears) I’m actually kind of nervous about this satellite.

What if I’m walking the dogs and, SMACK, a chunk of sizzling-hot spy satellite crushes me? Stranger things have happened.

How are the dogs going to get home? And if they get home, how are they going to open the garage door? They don’t know the code. Even if they did know the code, they can’t reach the keypad.
