Wendy genuinely likes hanging out with the twins and is genuinely Dipper’s friend, which just gets to me. I was (am) one of those people that loooved being a Junior/Senior in high school because I liked being at the top of the hierarchy. And yes, I was totally condescending of the overly loud freshmen trying to act like big dogs in the pig pen. By all means Wendy should be like that too, but she’s not. She’s chill, and relaxed, and super comfortable with who she is. She can have fun with the kids because she’s willing to let herself have some g-rated fun instead of whining about it. Case in point she has no problem going camping with her dad and brothers, whereas a bunch of other teens would probably bitch and moan, or at least pretend to. She gets a little jerky when she’s with her teen friends, but that makes her super realistic. At that age we all put up a front with our friends; to be a little harsher, a little more critical. She’s also willing to take advantage of Stan’s absence and Mabel’s kindness, which isn’t very admirable, but very realistic. She can also get emotional and angry, and seeing that cracked facade and honesty made her all the more affectionate for me. She’s just a pretty great character all around.
