Unconnected rhymes

Inside my filing cabinet
there lives a little mouse.
He's very sweet, he's very nice,
and nobody knows he's there!

Pinned onto my heart
there's a message,
especially for you.
It shouts "I LOVE YOU DARLING!"
"and always will do too XX"

It is my birthday next week.
A pile of presents wait.
Time is turning slowelly
for my 32-year-old fate.
