Both my sister and I had to make sacrifices when it came to organizing our room. Kathryn didn't like having a dresser so we made storage beds and got rid of the dresser. I love our beds but I liked having our dresser too. It gave us more space to store our clothes and a place to have a lamp.
We tried to compromise when it came to the dresser. We were given a bunk bed that had a trundle bed underneath. It had drawers, a desk, and a storage area in the back. In the daytime we would roll the trundle bed underneath and we would have a lot more room. But at night when ever someone rolled around on the top bunk the door to the storage area would open and close. Also we would hit our heads on the ceiling or the fan in the summer because the top bunk was only about a foot away from the ceiling. The bed didn't work so we gave it to someone else. We tried bed frames and storing some of our stuff under our beds but that ended up just being a huge mess.
I really liked having the dresser but my sister didn't. So I agreed to getting rid of the dresser and building storage beds.
I wanted to paint the trim pink and my sister doesn't like the color pink AT ALL. But she still let us paint it pink.
I know that it can be hard to "be last" but sometimes it's better to just say "Ok, we can do it your way" than to argue about it.
So if you try compromising something and nothing is working out then just remember, sometimes you have to be last : )
