suffer always

In LIFE can there be a day without suffering, can anything is permanent in LIFE?
No way , can anyone answer why this is so ,,???? no no.
but we get something we feel happy but after a while we feel again will it is with us permanently
or will it go off suddenly, why this things bothers us....why we think this way....
so what i would like to say suffer........... by having a smile on your face not water in your eyes..
