As the visitor in my fathers home I was very much that a " visitor" where as his then wife's dd (who also didnt live there) was very much " someone who belonged there" shehad her own room and clothes I slept in the spare room where their coats and winter/summer clothes was on a sofa no effort was made to make it a nice place for me where as she had a beautifully decorated room. (as did the 2 live in kids my brother and sister - a bit more understandable)
When they moved bro had a room and x step sis had a room i slept on the spare bed in my brothers room with nothing of mine allowed to remain. (big sister had moved out by then)
It was rare anything was done as a special treat when i was around but I was often spoken of what they had don the weekend before when the golden child was there. I was not permitted to come on full holidays with them were as golden child was with them for a full 3 weeks and taken abroad.. I was never permitted that when they went abroad I was not allowed to come and if they holidayed in Denmark I was permitted to come for 1 week. (stuff to be done for that week would be cut down)
In contrast when brother and sister came to visit at my home. Every thing was changed around and the focus was completely on what they wanted if I was not happy with them being in my room or using my stuff I was told off. in my mothers home my brother was the golden boy and my sister the golden girl.. I was just the boring ole same ole same ole.
My father remarried when i was 15. i got 2 new step siblings a boy and a girl. whilst I never had a room in their house they lived in the same town as my mother I was treated equally to the other children. stepmother no 2 was instrumental in ensuring my father finally ensured that at age 15 I learnt he gave a damn about me. I will forever be grateful to her about that.
Step mother no 3 had 2 children of her own but we were all adults (I a mother of 3 when they married) She never made any difference we were all 5 " their" children.. She passed away about 7 years ago now and my father is a widow these days.
With my mother my sister and brother always matters the most even now as adults, if i phone she will spend the conversation talking about the new golden child (my niece) Is rarely interested in my children.
My father learnt from his last 2 wives that if he wanted me in his life he had to ensure I felt he gave a damn. These days I know my father loves me and I know he cares.. But it was a though journey and when I look back at my childhood I often think to my parents "What the F were you both THINKING???"
So in my case me as the visiting child never got preferential treatment and me as the " stationary child" never got preferential treatment
My mother very much disney parented the 2 who didnt live with her and my father did a good job at making me think he didnt give a damn that i was the embarrassment.. I now know He did care he was just utterly appalling at showing me and didnt see the glarring differences he made.
Hence in a strange way I can answer yes and no to the question.
