Fabel Aesop

Two Travellers, walking in the noonday sun, sought the shade of a widespreading tree to rest. As they lay looking up among the pleasant leaves, they saw that it was a Plane Tree. How useless is the Plane!, said one of them. It bears no fruit whatever, and only serves to litter the ground with leaves. Ungrateful creatures! said a voice from the Plane Tree. You lie here in my cooling shade, and yet you say I am useless! Thus ungratefully, O Jupiter, do men receive their blessings!
