With what you were willing to tell us, there isn’t enough there for a story. It’s some character background, but if that background is going to play a big part in the story then yeh that sounds interesting, I wouldn’t describe it as “stupid” at all. If it’s just background for a bit of detail and motivation but not a major driver of the story then your friend and also I don’t have enough information to form a conclusion, because that’s not a story yet, but it’s still an interesting little bit of background that I can’t see why anybody would immediately jump to “stupid”.
