My parents are dead. But before they and my grandmother passed, I always had a home base. I could walk in, raid the food, put my feet up on the couch, ect.
DH's parents house is the opposite. You have to call and knock before going over. You have to ask before getting a drink. And forget about eating. They never, ever, offer to feed you, a snack, nothing. Their house is big, but they make sure its just for two. Tomorrow when we go for Christmas we will be sitting on the floor because they got rid of their furniture and have 2 recliners.
It makes me mad. My kids are adults and I always want a house they can come home to. They all have keys to the doors and never have to ask for anything. I usually start cooking as soon as they come over.
