Time heals everything, at least partially.
Due to my geographical location the twin-towers are (*ugh were*) very real to me. I wasn't the mushy-gushy type, but only lately can I watch the horror of those videos and not break out into tears.
Of all the events of that day the clincher?
Finally getting home from Manhattan, in a desserted city Manhattan is NEVER empty) getting to my car from the Long Island Railroad, only to find that NONE of the customary radio stations was on the dial in the right place. Stranger even was that TELEVISION stations broadcasting over the radio. Don't know why this affected me. Oh I guess the Emergency Broadcast System actually being used was bizarre to me as well.
The magnitude and repercusiions of the day took a few days to REALLY sink-in, in my head.
The land-line phones were out for other reasons, cell (mobile) phones were jammed and uselss. The only way to get in touch for me was AOL. Radios had been banned in my office a mere week prior.
