I am not necessarily saying wellness check - more just to be clear and make sure everyone is hearing the other even if it doesn't mean giving what the other person wants. For me with students - I want to make sure I understand what is really being asked before I can answer or that they understand what I am saying back = it is not to get everyone to agree or like what the other wants or won't do -just that we understand - not necessarily agree.
It might have been some checking to see if this was your normal way of upset or something different. From the outside - it seems more your normal way of interacting when upset so it wouldn't necessarily cause alarm to someone trying to talk to you as an adult. It might be frustrating but not alarming. I think a phone call to clarify or even check in is different rather than in a therapy session where regression may be more expected or at least not unusual.
