We're So Different Now (Rhyme Royal)

Seems all you want to do is criticize
When once we were the very best of friends
Once you were truthful, now you just tell lies
Time for our friendship to come to an end
There's no way this friendship can ever mend
Best friends forever was our childhood vow
Saddens me to see we're so different now.
