Okay, I don't know what to do...

So there's this guy and I know what you are thinking now but no. He however, looks at me all the time. It's been like that since my school trip to London. 

I went to London last year with school and there was this pretty cute guy who also came along. However, he was one year and one level higher in school than me (here in the Netherlands we work with school difficulty levels). Well, the trip was for people who were supposed to graduate te year after the trip, so it wasn't that much of a surprise. Anyways, I knew nothing about him.

Until. 

We were walking back to our hotel after a long day of exploring London and I went to look for one of my friends and I found her, walking next to that guy and she was talking to him. Turns out, they were very close friends in elementary school. That's how I came in contact with him. 

After the trip however, our contact kind of died and the only kind of contact we have nowadays is saying 'hi' when we cross paths at school. 

After a while, I got invited to a party from one of the girls who also joined the London trip. She was in the same year and in the same level as that guy and they are good friends. We hadn't had contact with eachother until most of the people went home. He sat on the couch, alone, so I went to sit next to him. It was kind of awkward after not having contact for a fairly long time. After the awkwardness was long gone, I saw him hestitating for a moment, but then he put his arm behind me. It was on the railing(?) of the couch but it still looked as if he had is arm aroud my shoulders and from then on, people started saying he liked me. After a while, people started asking if we were dating. Turns out, someone took a photo of us when we were sitting like that. I laughed it away but I still felt a little uncomfortable. 

After that, our contact died. Again. 

However, turns out he failed last year and he also had to go to my leel, which is one level below his previous level. I did not know any of this. Until today. 

We had P.E. and we went to a sportshall. As soon as I walked in I noticed him. Turns out we have P.E. at the same time. It went the same. Polite smile and hi. 

This time however, I saw him looking at me a few times. Well, a few... And it was almost as if he was staring at me with this weird expression. He never looked away or smiled at me when I looked at him. He kept on staring. 

During summer vacation, I never thought of everything that happened last year, but after today, it started bothering me again. I can't look inside his head, so I don't know what he was thinking about when he was staring at me... 

Please, some help or advice ?? Because I really don't know what to do with this...
