9. 4 GRAMMAR - Present Perfect with already/just/yet.

I can use the Present Perfect to talk about recent events.

Lee: Hi, Amy! What's up?

Amy: Have you bought the train tickets yet?

Lee: Well, I know exactly what train we want to catch - I've already checked the timetable.

But I haven't actually bought the tickets yet. I've bought a map of the Scottish Highlands!.

And I've just cleaned both the tents.

Amy: So you haven't started packing yet?

Lee: Give me a break! I've already told you - we haven't bought all the food yet so it's too early to start packing.

Anyway, have you heard from Billy yet?
