Am I a coward?

Friday morning.Five o'clock.In my sleep I hear two blunt noises and then smashing glass. I ran to the balcony door and see the back of a young man breaking into a shop opposite my house. I rush and phone the police. I continue watching behind the curtains.After a couple of minutes two young men get out of the shop holding something small.I can't see their faces.It is too far away and rather dark.They walk away.The police arrives a couple of minutes later.A neighbour who had probably called the police as well is talking to the policemen.I go out in the balcony.And then go back inside. I can't sleep.I feel such a coward.
Some years ago in a similar situation I screamed and the thieves left!This time I simply got scared. We have been hearing so much on the news about burglars and thieves who shoot eye witnesses!Yes I admit I got scared. I didn't scream. I didn't help out.
Am I a coward or a sensible person?
Still I feel bad about myself.I was thinking about it all day on Friday.
And all day today I am in bed feeling weak.The weather is bad so it is better to stay inside.We even heard our first thunder today!
Anyway it is impossible to walk in the streets and not feel bad. They are full of rubbish.For some reason rubbish is not collected.I phoned the municipality cleaning office and was told they don't have enough personnel.I read in a blog that the municipality has no money to pay for the gas for the rubbish collecting trucks!I don't like this Thessaloniki.It makes me want to get up,collect some rubbish and go and throw it in front of the municipality hall.But I am not doing it.
Am I a coward or a lawful citizen?
Seeing everyday what is happening in Japan and Libya and other countries I simply get back in considering that what I see in my neighbourhood is minor in front of these people's problems.
But shouldn't we start facing the small problems before we face the big ones?
