It’s not an afterschool special in Reggie’s family where they tell each other they love one another every day. Victoria is voicing something personal to a stranger just to hear it out loud. Sometimes it’s easier to talk to someone you don’t know that well & don’t really expect to interact with regularly, or possibly ever again. At the same time she probably hopes that what she says will make its way to her brother second hand, so he’ll know, but they won’t have to go through the embarrassment of actually saying it face to face. For some people it’s difficult to be earnest and sincere. Letting someone know how you really feel makes you vulnerable. It’s giving up power. That’s an aspect of love people don’t always think about. To tell someone they are important to you gives them leverage. If the balance should shift you are at a disadvantage. Unfortunately people exploit that every day.
