The most unexpected, the astonishing,
An experience it is, surprising.
A hope, thought and desire, unknowingly,
When come true, is surprising.
Happiness beyond words, thousand emotions,
A feeling of being loved, adulation.
Moment, of a new beginning,
Morale high, strength newfound.
Change too quick, be prepared,
Surprise is a moment, here and there.
Accept it soon, feel better now,
If you miss it, it’s a surprise gone wrong.
