I need punctuation help. I still don't always know when to use semicolons. As I understand it, you use semicolons when you want to separate a complex list such as:She needed to pick up a prescription from the drug store; a flashlight, batteries, and tape measure from the hardware store; and milk from the grocery store.
It is also used when you have a sentence with more than one subject, almost like two sentenes you're pushing together such as:
She was always the one to do the shopping; her sister was utterly useless.
Am I even hitting close on this one? How about htis setence, one I just wrote...which is it a comma or semicolon?
Kay did not trust her sisters, she never had.
I'm leaning toward comma but I'm having doubts.
