You'll never know

I see you playing together.
You both look to see if I'm watching
And I am
But you'll never see
The exhaustion
The tears
The frustration
Because all you need to see
Is me.
If I smile at you
Be it through tears
Through drooping eyes
Or through gritted teeth
All you see is a smile.
The hugs you both need
Are surrounding you both
With so much love
That I hope
You can feel through
The shaking
The tightness
The looseness
Because I want to give you
All the love I have
Regardless of the tears, tiredness, tension.
I hope you'll never see
Anything but love.
