I'm 18 and one of my mom's friend's granddaughters annoys me. She's just really, really hyper and there is just something about her. It's like she can't stay still for just a second. Now don't get me wrong, I love kids, but hyper people (in general of all ages) just rub me the wrong way. And I'm a pretty laid-back, introvert person. My mom has noticed my attitude about/toward her and made me feel really bad about it but I can't help how I feel about certain people and how honest I am about them. Plus it sucks when I want to hang out with her grandma (whom I really like and is a really cool person) and she has to bring along her granddaughter. Ugh, what should I do?
