Search Results: looking at chest

(I am 6 feet 3 inches tall, athletic build, big chest tattoo, 18 years old, curly hair). there's this girl whos 2 years older than me that goes to my gym that used to go to my high school. She was in grade 12 and i was in grade 10. Through the 2 years i saw her at school, she NEVER noticed me or glanced at me. I think that this was before my high school blossom period (I was 3-4 inches shorter, nerdy looking, glasses).

Now, i first saw her again at the gym back in May 2019, i haven't seen her in 2 years. I was working out and there's a mirror in front of me, so I saw through the mirror that she would glance at me every now and then. Around August , I was standing in the middle of the gym and when she goes to put her weights back, she's just staring at me as she's walking to put them back. 3 days later, I see her again working out with her friend. I walked past her and i saw her look at me at the corner of my eye. Soon after, i was sitting down on my phone and she turned the corner and was already looking at me before she turned the corner. That means she knew i was sitting there. Mind you, there's a water fountain in front of me. So she looks at me right when she turns the corner, drinks at the water fountain, lifts her head up, turns to look at me again and walks away with her friend. ABOUT A MINUTE LATER, her friend (didnt notice me at all before) turned around to walk back where im sitting and started glancing and looking at me too. Then her friend walked back to her. Lastly, my friend and I walked by her when we left the gym and he told me that she looked at me when i walked past. MIND YOU, I NEVER STARED AT HER FIRST IN ANY OF THOSE ENCOUNTERS. She would look first.

Also, those looks were not any evil stares, they were regular looks and she has a glow in her eyes i noticed
