Be present
Reduce the distractions you control
Put the phone or other tabs aside when possible, keep the camera stable and avoid walking through a noisy space during the first conversation.
If you need to handle something off screen, say so briefly rather than disappearing without context.
Take turns
Leave enough space for the reply
Connection delay can make interruptions more common. Wait a beat when you think the other person may still be speaking.
Ask one question at a time and respond to the answer before introducing another topic.
Close clearly
End with a complete sentence
When you need to go, say that you enjoyed the conversation and make the ending visible. A clean close is kinder than slowly withdrawing attention.
Do not promise another conversation unless you actually want one. Friendly and honest language is enough.
