No one actually uses the "She goes to another school" thing as a was to lie. It's just stupid kids that accuse anyone who has a partner that isn't conveniently at the same school lmao
Uh no, back in high school one of my acquantainces held a lie for something like 3 years that he had a girlfriend named x that went to y school. My friends and I ended up seeing the yearbooks for that school. We couldn't find a single person at the school with his girlfriends name. He tried to say that her real name was actually w, and I kind of just stopped talking to him afterwards. Never learned how that played out with people closer to him.
