Let me help you correct some of the most common advanced grammar mistakes.
There are two different phrases that often get mixed up. One is easy, and one is complex. But even the easy one needs to be explained, and the complex one, well, that one too.
The first is about past habits, or something that existed or was true in the past, but doesn't exist or isn't true anymore.
The second is about a feeling you have about something.
A – past habit or truth
B – a feeling (present, past, future)
