Once upon a time, there were two Frogs live together in a lake. In a summer, the heat of the sun had dried all the water in the lake.

The frog said to his friend, "We can not stay here much longer without water."

"The birds look for the forest to live in, while we frogs look for the water to live in." After walking long enough, they found a well.

"See ! Right in front of us, there is a well !", the frog said happily to his friend.

"Hmmm...", his friend replied.

"Let's jump into the well. This is a nice place to stay and for the food", the frog said to his friend again.

"Yes, yes ! It will be nice if we jump into the well now, but the problem is ... how can we get out again then ?", replied his friend.

We need to consider the consequences of our decisions. Sometimes, an interesting opportunity may be just like the water in the well...it's easy to jump in, but it will be impossible to climb out !
