So I’m gonna dumb it down how I see it (my level)
So for example, there’s m&ms in the skittles box. They feel like they don’t belong there, but they pretend to be skittles anyway. This is referring to someone being amab and identifying more female/enby. Once the skittles box is opened, the m&ms realise, “hey, I don’t belong here!” And they “transition” into being themself, by going into the m&m’s box.
I think that makes sense?
