Surfing on the new wave

Mornings brightened by greetings from friends,
A neat To Do List waiting to be worked on,
Brain storming sessions which never ceased to amaze,
Discussions with creative people sharing their innovative ideas,
Refreshing lunch sessions filled with anecdotes,
Cups of tea and friends to lighten a stressful day,
Flocking to cubicles to share the giver's joy and chocolates,
Mentors and well wishers to applaud each step forward,
Ecstatic moments when your project is successful,
My life was flooded with all of these.
Then, the huge wave of change engulfed it all,
And my present quickly receded into the past.
Why is it not obvious
that everything in life comes with an expiry date,
that water bubbles disappear with the passage of time,
that change is the essence of life..
