What is friendship?
That I can't tell
Why do we have friends?
That I can't explain
Who is a friend?
That I do not know

Friendship is fragile
Friendships are vain
Friends we hang out with
Friends we never can leave

Is it all worth the risk
To put your faith on someone else?
In all time we never can fathom
Time won't tell, time won't tell
In all of friendship we can be part of
Time won't tell, Time won't tell
