My Front Door Is

I'm doing something I don't understand What I am doing although I have planned Out everything yesterday morning I saw you walk by My front door is blue How about you Coming around to see me in the spring Mattress on my bed there's one sheet missing Since last July I don't know why I let you walk right pass My front door is green Have you seen Anybody with a name Should know how to spell It unless he is insane And I'm very well Thankyou I do know how to knot my tie Is covered completely with letters I Owe to you I promise to pay you back should you Pass My front door ready at last
