I'm a mood reader, and because I cannot decide what I wanna read, I'm currently reading 4 books at the same time 
@itsbanhmi Most I can manage is an audiobook and a "normal" book at the same time or a german book and an english book, but no more than that or I get confused haha
@chaotin Usually I try to keep the maximum at 2 (ebook & audiobook or physical copy), but my brain cannot decide, so I have to live with that hahaha
