I'm a freshman and I like a senior. I think he likes me too but I'm not sure. He and his friends are always looking at me at lunch and I just wish I knew what they were thinking about me. One time I even saw him nod at me to probably ask his friend's opinion. I see him a couple of times a day but we never really glance at each other. Even if he did acknowledge me and wanted to go out, he's 3 years older than me and I can see people not liking us together. I don't know whether or not to approach him but I feel like I need to do something. So, does anyone have any ideas?
