How long do you wait until you know you have been stood up on Zoom?

It has never happened to me before!

I was ready, notepad, pen, diary and cup of tea.

11.00 - Start Meeting, No one there, Ok, I’ll check my phone and keep an eye on the screen in case I need to click Admit.

11.03 - “I’ll wait till 11.05 and I’ll send a polite message to let her know I’m Here”

11.05 - send message

Sitting staring at myself through the camera on my computer. Waiting, “the colour of my top looks different on screen”, check phone. Waiting, send message to school friends group. Waiting, check I still have pen. Waiting, check the polite message has been opened, nope. Waiting, send another message to rearrange meeting. Waiting

11.15 - Leave Meeting. Bitter Sweet – I have gained an extra hour Woo Hoo.

15 minutes I waited is it long enough? I guess it was in this instance as I never heard back, I could still be waiting!

How long would you wait? Is there a rule?
