It has been already 8 years after we left Gravity falls, and it has been 3 years I last saw Mabel. U know after we turn 17 I left becouse uf studies. It was becouse I already finished high school, so I left for college. Mabel wasn't happy but I needed to go. Now I already finished it, I skiped another year, and I gonna do anotherone. There is one little thing I forgot to say...
