Sorry If I Seem Sad

I'm sorry if I seem sad.
If when I look upon you
I see the deepest desires of my heart,
I cannot claim.
I realize the completeness long searched for,
that I will not attain.
Joy and comfort at the taste of your affection
now turns to pain.
I think of irony in a circumstance
not understood by my brain,
denying a happiness seemingly easy to obtain.
I look into your eyes,
and glimpse at a future that is not mine.
Like peering at a window...
seeing my dreams reflected in the pane.
I'm sorry if I seem sad.
