Narrative:

On the ground at geu; I had gotten clearance from geu tower for takeoff from runway 1 to do closed pattern touch-and-goes. When cleared to enter onto the runway and takeoff; runway 1; without any precautionary statements nor further instructions; there were no other aircraft taking off ahead of me nor did I hear the tower communicating with any other aircraft. I took off climbing about 500 FPM at 79 KIAS; then turned downwind and noticed another similar aircraft lateral to me about 200 ft and 200 ft above. I was vigilant because I did not know his intentions. Then the tower informed me that there is an aircraft at 9 O'clock position. I acknowledged and I said that 'I have him in sight' and awaited further instructions from the tower. I also heard the tower notify the other aircraft of my presence and the pilot acknowledged. Then the tower said to me that 'I told you that you are #2 to land behind the cessna' who was beside me. I responded that I never heard any such communication. My passenger; a pilot; also said to me that he never heard any such instructions. We were both surprised to see that aircraft beside me. I then repeated the new instructions to the tower that I will slow down and land behind the indicated cessna. Then the tower told me to land ahead of the cessna; and I repeated that I would land ahead of the cessna. I heard on the radio the tower indicating to the other aircraft to land behind me. The other pilot responded that he will slow down and land behind me. I then proceeded to do my touch-and-go and do another pattern circuit. I radioed the tower midfield downwind and asked to do a full stop landing. The tower responded clear for touch-and-go. I then repeated that I am requesting a full stop. The tower then responded; 'clear for full stop.'
