a pair

I have a pair of eyes,
but those fell victim to your sight..
Also a pair of ears,
but they don't listen to friends' advice!

I use a pair of lungs,
but air is hard to pump inside.
Just like the two parts of my brain,
creativity and reason just collide.

I have a pair of hands
with those I held you oh so tight!
But with a pair of legs
for you was easier the flight...

I have one heart
and I gave it all to you
I need to grow a pair now
to get over all I put myself through!
