Under the mat

I'll leave a key under the mat for you, and one with the neighbours. I'll send you one in the post. I'll wait in, if I can, and if I can't I'll put a note on the door saying just where I'll be so you can find me. I'll leave a vase of sunflowers in the window so you know which house is mine, and a trail of petals all the way to your door. I'll leave a key in the lock for you. I'll take the door off its hinges. Please come. I can't live locked up here any longer.
