Forget or leave?

We sometimes use forget when we don’t remember to bring something with us:

I’ll have to go back; I’ve forgotten my car keys.

We use leave with this same meaning, but only if we mention the place where we left something:

Mia, you’re always leaving your car keys on your desk.

Not: … forgetting your car keys on your desk. or … you’re always leaving your car keys.

I left my homework at home.

Not: I forgot my homework at home.

We use leave when the action is deliberate:

We decided to leave the dog at home.
