Kay - all i am saying...i guess it depends on how well you know that person.
If you came home roaring drunk, and woke her up expecting s## at 3 am - that would piss her off right? And you would know that. Right?
So, maybe it isn't something so obvious, but may have made her just as mad.
Think back to the day she got mad...oir quit talking. Did you say something offensive (women can be stupidily sensitive...)
