All the plates disappeared and no one is disturbed

I’m apart of a huge Mexican family living under one roof, so we have a lot of plates. We have large plates, medium plates, and small plates. We especially had a LOT of medium plates, because they were so convenient. Then one day, I don’t know when exactly, all the medium plates up and disappeared. Like it wasn’t until a month ago did I notice. I asked my whole family and some of them don’t even remember the plates existing in the first place and all of them don’t care about it. Like what the hell, where the fuck are my plates. You’d think there would be at least one left, but there ain’t shit. I know this ain’t normal, but I’m going mental over this.
