In my experience, assembly makes you do a lot of busywork over and over to achieve certain constructs. Loops and function calls come to mind immediately. They're not hard things to do in assembly, but you'll need to write those every single time you need one. So then you start making macros to handle this for you. By that point the conceptual leap to C isn't very far.
