Inconvenient

A fragile heart is a very inconvenient thing to have
It doesn't matter how, once it's broken
People are clumsy or careless all the time
A word here, a gesture there, and whops it goes
So make sure to encase it well, always build up strong walls.

'Cause a broken heart is a very inconvenient thing to have
You have to walk carefully, not to spread the shards
You can't breathe deeply, the cracks expand
You can't even laugh properly, for fear of shattering the whole thing.

All you can do is to slap a band-aid on it for a bit

And look for something else to distract you, while it heals.

Here's the thing, a broken heart is indeed a very inconvenient thing

But there are worse things to have, for sure

You could have a wart on your nose for example 

Or blisters under your heel, wouldn't that be bad?

A broken heart eventually mends itself and you're the wiser for it

And believe you me, scars start way more interesting conversations

Then first editions in pristine condition...
