帮忙写一封英语情书.

WHEN YOU ARE OLD
　　WHEN YOU ARE OLD AND GREY AND FULL OF SEELP
　　AND NOODING BY THE FIRE,TAKE DOWN THIS BOOK
　　AND SLOWLY READ,AND DREAM KF THE SOFT LOOK
　　YOUR EYES HAD ONCE,AND OF THEIR SHADOWS DEEP；
　　HOW MANY LOVED YOUR MONMENTS OF GLAD GRACE,
　　AND LOVED YOUR BEAUTY WITH LOVE FALSE OR TRUE,
　　BUT ONE MAN LOVED THE PILGRIM SOUL IN YOU,
　　AND LOVED THE SORROWS OF YOUR CHANGING FACE；
　　AND BEDING DOWN BESIDE THE GLOWING BARS,
　　MURMUR,A LITTLE SADLY,HOW LOVE FIED
　　AND PACED UPON THE MOUNTAINS OVERHEAD
　　AND HID HIS FACE AMID A CROWD OF STARS.

The only i want to say I love you

Only you
