You are a lifeboat on my sea of blue
and though it seems calm and bright,
you remain to be my guiding light.
It may seem like I do not see you,
but believe me when I say-
I see your light even on a foggy day.
I'm so glad you became my friend,
and I will cherish our days together
from this day until forever,
and hope you feel this too in the end.
I wish to say thanks for everything-
I hope you know that what I say is true,
in this poem that I have given to you-
though it may not seem like anything.
