Lmaooo that's honestly hilarious. I mean let's be real, what college students wants to go out with a highschooler? And one your brothers age at that.
I got asked out by a teen my brothers age the other day and I had to use all my adult wisdom just to not laugh in his face and ask him if he wanted me to catch a case. Kids don't think about that but c'mon.
Right now it's cute and lighthearted so it's fine but I really do hope they don't get together. And if they do, at LEAST let him be in college as well I won't complain then...even if I still want him to get a gf
