Where I was... on 11-M
I don't remember the exact details about that 7/7, I recall hearing the news at the morning and thinking that the power surge was somewhat fishy.
What I really remember is 11-M. Because I'm from Spain.
I heard nothing before leaving home. I took Cercanías trains without any disruption up to the university. Just like everyday. Note, however, that I was at Barcelona, not Madrid.
Nobody knew anything at class at first. The first term passed uneventful. Before the second term, some of us noticed a faint smell like coming from a gas leak. Some minutes later, we were evacuated from the building, all believing due to this gas issue.
It was not until 11pm that news surfaced all around the campus. Bombs at trains, which most of us use to ride to the campus. Some said that there were also bombs at Barcelona's network. That was a false rumor, but impossible to know at the time. The silence was terrifying: most of us thought that it could have happened to ourselves.
I do not remember that 7 of July. But I do remember very well that 11 of March. And know what terrible feelings go through everyone's bodies.
As with London, the death toll was unbearable. Not because it was higher, but because just one single death is too much.
I can understand too well how do you feel.
