Finish the book I borrowed from my high school english teacher so I can return it to her

I woke up this morning pretty early (for me, which was 830) from a friend texting me, and I couldn’t fall back to sleep, so I grabbed the book and read for a bit. 50 pages in not much time at all. It’s a very good book, and when I’m reading it I really enjoy it, but I’m just shit at actually sitting down and doing just that! But I wanna get this book back to the teacher, so I’m trying to push through. Honestly? I kind of think sitting in a different place might help with that. I’ll try out my sofa.
