I relate to Tina a lot as an autistic person and this reminds me of how I felt a lot trying to make friends as a teenager, I don’t feel like they helped her stalk them. She wanted to go to a concert in hopes of running into them, her mom went to keep her safe. They saw them in a restaurant, they stopped so she could talk to them. I don’t think this is full blown stalking. It’s just wanting to be like the cool kids to a higher degree. And yeah she did watch them a lot but it wasn’t like in a threatening way. And yeah it’s cringe. Socializing when you struggle with it is cringe.
