You were waiting for the bus when it began to rain. If you want to chat with the person next to you, what kind of conversation can you start?

If you want to write this dialogue, you can start with the weather, for example, what a heavy rain! I don't know when it will rain. And that is to say: for example, you ask the other person which bus to take? Why hasn't the bus come yet? Could it have something to do with the weather? Then design this dialogue.
