She was ugly :(

I did my best to be prepared me to meet that girl that I saw last week, and I liked her. I was very confident in the morning, but 30 minutes before going there, I had lots of stress. I don't know why. I went to her class, and I saw her. I don't know maybe I didn't see her, and I saw somebody else. I tried to pretend that I wanted to know about the class. I approached her, and tried to ask a question.

Me: "Hi. Is it Dr. W...'s class?"
She: "Yes. It is." [So what?]
Me: [Oh my god how ugly is she. Is she the same person or she is another person.] Do you know the topic for today's class?
She: No. I don't know, but the TA is standing there. You can ask him.
Me: Which one is the TA?
She: That one. [Now go].
Me: Is he teaching or the professor? [Let me see you more, is that you or you are another person?!]
She: I don't know. Go and ask himself. [Leave me alone.]
Me: "OK. Thanks."

And I left her. I asked TA about the course, but I really didn't want to know that. When I came out of the class, I tried to look at her again. I don't know if she was the same person or not. I looked at her several times, but I couldn't remember the girl that I saw last week. She put her hand under her chick, and I realized that she should be the same person. Maybe she wore another shirt, or had another bag, but she had the same habit of putting her hand under her chick.

"What a mistake I made. She was ugly. She was completely different from last week. Maybe it was not she. Maybe I met another girl. I was interested in a wrong girl, and I thought about seeing her all the week. I liked the girl that I saw at the library today, but I didn't talk to her because of this ugly girl." I thought to myself. Maybe she was not ugly, but I didn't like her. This was the story of my potential girlfriend.
