If you forget my birthday 
And make a mistake
You'll still be my best friend.

If you forget my birthday
Make a mistake and
Don't say goodbye
You'll still be my best friend.

If you forget my birthday,
Make a mistake,
Don't say goodbye and
Copy my test
You'll still be my best friend.
If you forget my birthday,
Make a mistake,
Don't say goodbye,
Copy my test and
Ignore me at lunch
You'll still be my best friend.

If you forget my birthday
Make a mistake,
Don't say goodbye,
Copy my test,
Ignore me at lunch,
Talk behind my back and
Betray me
Do you still have to be my best friend?
