Try

Plaster a smile

When my

Tears remain

Or call them

Tears of joy

When i cry in pain

Try and tickle a laugh

When I am

Slit in half

And try reverse a frown

When my

Mood is down

But a day will come

When the mask

Falls off

Then they'll see

What i have become

Then try and cover up

These broken tears

Which will now unleash

All your fears
