You're not stupid. And i know your feel, i couldnt really get into Homestuck. It was boring for me, i dont get the idea of it, like why is it so popular? I think its boring, but anyways. Its supposed to be about some kid i think?
Just read some meer of it you'll probably get into it later. I mean it's very complex and you'd probably understand it better if u read meer of it and try to follow it at your pace because if I were to explain step door step to the point where I am in it I'd doubt you'd understand.
