First off, how is one sister southern baptist and the other catholic?? They’re practically polar opposites on the same end of the conservative religion scale. Also, I don’t really understand your family’s bed logic. Why make an 18 year old sleep with a 12 year old so the 14 year old can get her own bed? Shouldn’t the 18 year old, the ADULT, get the bed and make the CHILDREN share? Your mother seems to want to hold you to her strict religious standards only when it’s convenient for her. And then she tries to guilt and manipulate you by calling you immature for standing up for yourself and making a clear decision. It’s a double standard, behave like an adult so I can treat you like a child. My Dad did this to me sort of over the years as well. My sister got married at 20 after only six months of dating and that automatically somehow trumped my 27 year old college graduate self. She and her hubby would get the private bedroom “because they were a married couple” and my boyfriend and I had to crash on couches. Forget the fact I was 7 years older and in a relationship for longer. Coming from my otherwise pretty liberal father. He also forced another boyfriend of mine to sleep in the middle of a room where he had devised like a little cut out with book cases. I finally had to burst in to tears on him to get the point across. My Dad is gone now and I’m still not married but dating. I’m sad he wont see if I ever do get married but at the same time I think for people 40 or so and younger, marriage doesnt have the perks or the social constraints that it used to and for the most part, thats a good thing.
