Emotionless Friend

Not once since had I seen you
To display such emotion
You were always so cold
Even around me your best friend
You've never shown such emotion
So why are now things so different?
What's changed?Something
Inside you must have awakened
Now you're so strange
So careless and free
What happened to the person
That you use to be?
Please return to your former
State,because seeing you like this
It doesn't feel the same
