Always, always, always, go back and make sure that what the interlocutor said or wrote, it is what was meant.
Often I find that miscommunication happens when the person(s) is writing or saying something in the “heat” of the moment of when tings are not going so well on their side of the fence.
When nervous are calmed, the path for discussions and further understanding is open and the miscommunication is properly handled.
Unfortunately in a world of ” emails”, is easier not say what was not really meant to be “communicated”.
