Excuse me, I've been waiting here for fifteen minutes. Do you know why the traffic is so heavy?
A lorry overturned on the road and blocked it, so all the traffic was held up.
Oh, what a terrible situation! This traffic is unbearable.
Yeah, traffic was brought to a standstill by the accident. If we had gone early we would miss the traffic.
I agree with you. But now we have to wait. The sky is overcast, and it is very sultry. I fear a thunder storm is brewing.
Don't worry. The traffic jam is said to be over soon.
Yes, I hope so. Thank you for telling me this.
It's my pleasure.
