What is a normal brother-sister relationship?

Anonymous

I was born in the contryside of my country. When i was about at the age 6 my family moved to a big city. We moved from countryside to a big city so we just had enough money to rent our small apartmant. My sister who was 2 years older than me and i was using the same room. We didn't had an extra budget so mom and dad was showering at the same time. Me and my sister was showering at the same time to keep the bill low. This wasn't strange to us. We were having fun regardless of our body deferences. We never had any trouble. Actually i really find it interesting that sister-brothers fight these days. This continued till i was 20 and she was 22. I needed to move out for work reasons (In my country school finishes at 19 and i got offered a pretty good job for 1 year experience). After i moved out things happened. I got a girlfriend. We got pretty close in few years. Now i am 25. I proposed to her and i am going to meet her family *officially*. She was always telling me not to speak with her brother and i was asking why. She was just saying complicated, complicated and complicated. (Side note this is my first time seeing her brother because he lives abroad.) I didn't want to make her angry so i didn't be so insistent. I am guesing that they haven't been talking for 4 years because her parents said something like that last year. What might it be? Was my realationship with my sister was strange? What is your relationship with your sister/brother?
