I can’t wait for Saturday! We are going to have / 're going to have a good time at the concert together! (have)

For sure! Will you need a lift? (need)

Thanks a lot. I’d like that. My train gets in at three in the afternoon. (get)

Ok, it’s a date. I will be waiting / 'll be waiting for you at the station when your train arrives. (wait; arrive)

How about next week? What are you going to do then? (do)

Most likely I will not / won't stay at home. I might go to Helsinki to meet up with my friends. (not + stay)

You know what, I will join / 'll join you this time if that’s ok? (join)

Great! If we take the earlier train, we will have / 'll have more time for shopping. (take; have)

Once we get there, we will not know / won't know which shops to visit so it’s best we plan ahead a bit. (get; not + know)

By this time next week we will have made / 'll have made a lot of arrangements already, don’t worry! (make)
