Tell me why?

As a child I was taught to trust
I was told making friends is must
I was taught to love & care
With friends I was asked to share
I was shown all the beauty of life
I was given aims for which to strive
With love & lament I was reared
I say again, I was asked to love, trust
and care.
But why wasn’t I shown the dark side
Not told that in hurting other people take pride
Why wasn’t I told that actually no one dares
No one actually for a grieving one, cares.
Why wasn’t I taught that friends are a drama
Why wasn’t I told about ceaser Brutus but only
krishnaa & sudhama
Why wasn’t I told that trust is also shattered.
Why talk about rivers & not deserts ?
