Vaka

You sigh low tonight
You're so alone
You're so
You sigh low tonight
You're so alone
You're so
You're so low
You're so alone
You're so
You sigh low
You sigh low
You're so
(You're so)

You sigh low tonight
You're so alone
You're so
You sigh alot and fight
You're so lost
You're so
You fight so low
You're so alone
You sigh low
Your sighs are low
You're so
