Knock, Knock, Knocking on Families' Doors

Benjamin Franklin said, "Fish and visitors smell in three days." Good advice, but I don't think he ever said anything about how family members should act when visiting another family member's house.

I bring this up because twice in the last week I have had an aunt (two different ones) show up at my door, knock twice and immediately open the door.  No waiting, nope, not for them. 

Thursday morning was the worst. My dad's youngest sister showed up, knocked twice really quietly and then just opened the door.  I wouldn't have had time to react if I wanted to.  I was asleep in my chair in the living room because I had just taken my strong pain medication because my hand was hurting really bad.  When she opened the door, the sun came in and pierced my eyes like a dagger.  She apologized and immediately left, but I was mad.  Even if she is family, she should at least wait for me to tell her to come in.  What if I was naked or something? It is one thing if you are expected, but it is entirely different if you are popping over to someone's house unexpected.


Now I go to my parents' house and will usually just walk in the house, but I used to live there, so it is a little different.  Even so, I still usually holler that I am there. 


Am I alone in this assessment? Has anyone else had family members that insist on barging into your house?
