Unknown love

No one could ever take the place of you within my heart.
You'll be there for eternity, no matter if we part.
Cos you're that special person who makes my day worthwhile.
I know when you walk in the room that everyone will smile.

So much you've had to deal with, yet your still as good as gold.
You're patient, kind and loving, though you're never really told.
Everyone adores you from the old ones to the small.
But the love this one girl feels for you is the greatest love of all.
