Also to everyone saying he’s thick (because I feel like playing devil’s advocate): imagine if you were like him, and just helped some people when you were like 8 years old. Idk about you but I can hardly remember anything specific that happened when I was 8. How tf is he supposed to remember that incident if it had no impact on his life and it was something he did all the time? If you’re going to ask why the girls remembered, then that’s because it was a major event in their life. For him, it was just another day going to his favourite bookstore. He’s not thick, he just doesn’t have a superhuman memory.
