twin boy

The other night I met up with a friend and saw the art exhibit here on campus. She had just gotten out of a lecture about medieval illumination and I enjoyed hearing about what she had learned. End of day one. Day two, I go to class, and my French professor asks me how I enjoyed the illumination lecture. I didn't go, I said. Confused, he repeated that he saw me there. I shared that I had talked to a girl about it, but that I certainly did not go.
I texted this situation to said girl. To my surprise, she confirmed the presence of this mystery twin. She said that she even thought it was me at first! I must find you twin boy. Whoever you are, whether you are evil or nice, I want to meet you.
My name is Nathan and I look just like you.
