You and I

I am Twitter and U are my tweet,
I am a scribble pad and U are my light pen,
I am a doctor and U are my stethoscope,
I am a magnetic north pole, U are the south pole,
I am a flower with nectar, and U are the bee,
I am a Java socket, and U are the thread,
I am a contest, and U are the prize,
I am a child class, and U are my protected object,
I am Dennis and U are the menace,
I am an angel and U are my wings,
I am a psycho and U are my knife,
I am a candle and U are my light,
I am a streetsmart dog and U are my bark,
I am an album and U are the picture,
I am a nomad and U are my map!
