- Choose the waiting point and the time after which you will take the next action.
- Make that action clear, such as going inside or returning home. Avoid leaving the other person to infer whether you are still waiting from message silence.
A worked example
“I’ll wait until quarter past, then go inside and meet you there.”
An invented example to adapt, not a real exchange or a script you have to follow.

Treat the stated plan as practical information, not a punishment for lateness.
