Imagining that Thomas, Bruno, Percy, and Diesel used to be TERRIFIED of Harold when they were babies because they literally did not leave the yard without an adult (and even then the adults rarely moved them) back then and so they got adjusted to existence and kinda just assumed rolling stock and humans were it, and then suddenly there is something BIG and LOUD and it can FLY and also talk??? They'd all have been terrified at first until Harold was properly introduced to them. After they adjusted to him and decided he wasn't scary anymore, they actually started to get excited when Harold flew by. He'd make stops now and then to meet up with the kids, found it cute how absolutely fascinated they were by him.
