I was coming here to say this. Charles Dodgson was a maths professor who was probably in love with his 12 year old neighbour, Alice, for whom he wrote the stories. The whole nonsense of things changing sizes and stuff was thought to be a bit of piss-taking at some of the "wild new math theories" happening. But also, yeah....sorta inappropriate feelings to young Alice, probably.

That being said, it's one of my all-time favourite books and I'm a big believer in just enjoying it for what it is - a fun, wild, silly adventure.
