A shoulder...

"... And when you need
A shoulder to cry on
when you need
a friend to rely on
and the whole world is gone
you won't be alone
'cause I'll be there
I'll be your shoulder to cry on
I'll be there
I'll be your friend to rely on
When the whole world's gone
you won't be alone 'cause I'll be there ..."
(a shoulder to cry on - Tommy Page)

Everybody have a shoulder, and everybody need a shoulder....
we can't live alone....
