How to send a circle of friends when you are stood up?

Being stood up can send a circle of friends like this:

The happiest thing in the world is to travel with an unreliable person, and he left me alone on the side of the road.

Everything planned has suddenly changed, and this feeling is really uncomfortable.

I've been waiting for you to show up, but you stood me up and left me here alone.

Didn't we agree to start together? Why did you stand me up and let me wander here alone?

6. I try to make myself better so that you won't stand me up again when we meet next time.

7. It's not that I can't travel alone. I just don't want to experience being stood up again.

8. I was stood up. I just want to say one thing to you: I'll make an appointment next time!
