A Bomb Scare!!! Yikes!!!

These past few weeks I have had the good fortune of eating tasty traditional food. I had Karimeen pollichathu...which is yum and worth the effort. Karimmeen being full of "fish bones". u really got to be careful. You don't want to call an ENT. I noticed how authentic the pulissery and pickles and fish curries are in the hinterlands of Kerala.
On another note,something funny happened the other day. I was on this train and had a window seat.The single seat. Suddenly this guy comes over leaves his briefcase on the opposite seat and walks away. I looked where he was going. No he did not heaad for the restroom. He went further into the next bogey!!! I looked at the brief case . It was locked. It was of brown leather. Was a bomb ticking away in it? And why had he chosen to place it near me of all persons??? I looked at it and all kinds of thoughts arose. The guy in the next cabin looked at me. I told him my suspicion and he laughed. The old lady in my cabin who was lying down laughed too. But she had a kind smile and twinkle in her eyes as she slowly arose. I went and sat opposite her. Then we started chatting and I felt better. Then the other guy, the owner of the case came and sat down, not knowing the commotion he had caused. We told him and he said he was lucky I did not inform the TTR.
I think I should ideally have called the TTR. Also maybe run to another cabin instaed of sitting in the same one.
What say u all? What should I have done?
