tell me why ,why do you cry,every time we say goodbye

tell me why ,why do you cry,every time we say goodbye
歌词如下：
tell me why ,
why do you cry,
every time we say goodbye?
do you believe,
i'm gonna leave you for ever
this time?
tell me why ,
look into my eyes,
why can't you see,
that i believe in you and me,
is it because,
someone else was unture,
and made you cry?
tell me why ,
in the time that we've been together,
we've seen the seasons change,
but my reason for loving you,
is still the same,
so tell me why:
why do you cry,
every time we say goodbye?
why can't you see,
i want to be with you?
you know it's true
tell me why.
tell me why.
