M: How did you like the fireworks last night?
W: I really didn’t enjoy them too much. There was such a big crowd that we couldn’t get very close.
M: I thought you were going early.
W: We did, but even though we got there at ten to eight, the park was already filled with lots of people. It was so crowded that we had a hard time finding a place even to stand.
M: That’s too bad, because the fireworks were really wonderful.
W: What did you do? How did you manage to get a good view?
M: We went early. We decided to have a picnic so we’d be sure to get there early enough to find a good place.
W: I guess that’s what I should do next Fourth of July.
M: We found a place on top of some rocks where nobody could get in front of us.
W: What did you do about going home? I’ve never been pushed so much in my whole life!
M: Oh, we stayed around for an hour or so, but they ran extra buses until midnight, so we didn’thave any problem.
W: I think you were lucky.
M: It wasn’t lucky. It was a good planning. You’ll have to come with us next year.
