You can’t say that you’ve truly tasted an awkward pause until you’ve visited someone in their home unannounced to converse about a topic that is dear to you but that you haven’t yet developed the skill to communicate.
A pause is a moment.
It is a natural break in the rhythm of a conversation.
It might indicate that the other party has been taken aback by what’s been said.
It could signify that they are thinking about what you’ve just shared.
It might happen because you are both marveling at this new ground broken in your relationship, so alien to daily life.
Occasionally, it is all four.
