Life is all but a simple and challenging holiday. It starts all nice today, but in the middle, it gets all rocky, and you are stuck. You don't know where and how to get rid or to avoid all those rocks that are in your way or keep coming, so when the time finally comes for you to get ahead in life . . ., oops, it stops. The train of life ends as the gas ends, and "thud", there the holiday ends, and you return to your original home, which is heaven to almighty. Thus, don't trust life as it's but a simple and short holiday that can end any time, any day.
