The Two Frogs

Two frogs dwelt in the same pool. When the pool dried up under the
summer's heat, they left and set out together for another home. As
they went along they chanced to pass a deep well, amply supplied with
water, and when they saw it, one of the Frogs said to the other, "Let us
descend and make our abode here: it'll furnish us with shelter
and food." The other replied with greater caution, "But suppose the
water should fail us. How can we get out again from so great a depth?"

Do nothing without a regard to the consequences.
