Feeling a Bit Resentful

Strange how one's past sometimes can jump out and surprise you.
On my way home from where I am currently working, I catch the bus from the bus station in town. This evening as I approached the stand where I catch my bus there was a bag sitting on the bench with no-one apparently in attendance.

Given recent events in Bali, my heart sank and immediately looked around for a security type person. Telling him of my concerns, I was surprised to see him just amble over to the offending item of luggage and just stand there looking around for a possible owner.
As he did so, I found myself moving to put one of the support pillars between the bench on which the bag sat and me. It was at that point I realized that a behavior that had been emphasized in my very first job working in a bank (lo, these many centuries past in England) had reared up and acted without me.

When I first started working, the IRA had a nasty habit of leaving unattended bags in shops that had a tendency to explode. Here I am, reacting in the way I learnt way back then, because someone had left a bag unattended.
On one hand it indicates the still trusting nature of Australians that someone would feel safe enough to leave his bag on a bench in a public place while they step away to talk to friends. On the other hand, my reaction to seeing an unattended bag indicates the extent of my own unconscious awareness of urban terror.

I hated the feeling of disquiet that afflicted me when I knew there was a bomb alert in town, back then. I resent that a similar disquiet reared in me today just because recent events have brought memories of terror closer once again.
