Friends come and go
but the loyal species are hard to find

I'm not good at making new friends
but when I do I try to keep them close

My heart isn't an open book
it stays under lock and key

My shell is hard
while my inside is sensitive

So these friends are sacred to me
and when i part from a good friend
it slowly leaves a vast space in my heart
til it slowly heals on its own

My mouth usually stays closed
but there are those special people who let it free

Friends are those who keep you close
and never let you go

But to find them drift apart
What can you do other than to set them free?
