I can hide!!

I can hide your fears,
I can conceal your tears and your nervous feelings.
I can veil up your silly stupid thoughts,
that you have been wearing since years.
I can manage your tensions in weird situations,
I'm your best friend ,when you go blank.
I will easily cover you when you are in dark.
I can help you pass any kind of examination !
I'm not real , intentional ,cleaver or smart
still I help you out easily during your odd moments ,
I can help and hide your pain and broken pieces,
said the smiling Lips , to the broken Heart !!!
