Dream Interpretation.........?

This dream wasn't worrying or anything, just out of the ordinary in my mind. It's only one part of my dream so it's not much.

I was sitting in a bus, waiting for it to leave the depot. Where I live, you can ask the bus driver to wait a moment if someone's running late, but for some reason this was a city bus. I saw my sister and my friend (they have never met each other) walk into the depot and I was annoyed because I thought they wouldn't make the bus. A few minutes passed and the bus began to the leave the depot. They were just standing there watching the bus leave. Before it reached the road, I hopped off the bus and took a long route around the depot. It was nighttime and it was raining. When I reached them, they apologized for missing the bus. My friend was wearing a suit that was very ill-fitted.

It's nothing really but any interpretations?

Thank you in advance!
