After 9/11 there was a spate of marriages and people going out to do things they have waited for a long time to do.
At some levels this is happening in London too...people know life is unpredictable and things change and you may never get to see the face of the person you love the most again. There might not be a 'someday' or a 'sometime'...the time is now. Now is good!!!
Its sad to note that something as gruesome as a bomb makes people sit up and realise that freedom, health, liberty and security is not a god given right ...and should not be taken for granted.
Everyday is good. Time is now. You know what to do. Do it. Just do it..dont think...dont deliberate..just walk out and do something today that you have been meaning to do for a long time.
