Programming is about aligning what the code should do, what you think the code does, and what the code says. Intent, mental model, syntax. If any of these pieces is out of sync, your code doesn't work.

Debugging is the process of identifying and fixing the mismatches between the 3. Mismatch between mental model and syntax = easy debugging Mismatch between mental model and intent = hard debugging

Mismatch between mental model and intent = bugging!

This is so accurate! Thanks for summing it up, next time when I debug, I can use this is idea to find what I'm missing.

the hard debug is when the syntax does not equal the intent.... when the mental mode can't see its fault.

Many a time the 3 things happen to refine the intent which in turn make you go through the 3 things again. That makes it even harder.

Reason 45 why SCRUM creates bugs: Starting coding before you know the intent and have no mental model, is a sure fire way to create bugs.
