I am a younger sibling and i shared a room with my sister when i was younger, if the teenager gets their own room the younger sibling gets their own room! People need their privacy. If i was still sharing a room with my sister we would fight way too much.

 Teenagers should have their own room, because that's about the time when there is a huge separation between the two, eg, the older one staying much later, and I believe that teenagers really need their privacy, without having younger siblings get in the way.

 I hate sharing rooms my oldest sister and I used to rooms about4 years ago when I was in middle school and she was about 19 she smoked, drank and anything else My room was always a mess, it smelled, I spent hours very week cleaning the while room to make it better. She also worked graveyard so she would be very loud when she would get ready for the work. Now I have one of the biggest rooms in the house and I LOVE my room I love my bed and I love how I painted my room.

 Yes they need space

 If they are the same sex I think its ok.

 I did that it sucks i think they need their own privacy but yes they should in case you need them their always their

 I don't mind sharing a bedroom with my siblings...after all, I don't do much in there besides sleep...

It's a little crammed but I don't mind....

 Yes everyone needs their own space but it doesn't always work out that way. Too many kids and too little bedrooms. I offer my oldest of 3 the front entry way every time she is in need of a bedroom minus her younger sister. She never takes me up on it.

 Yes their own bedroom

 I totally agree. Up until a few months ago my sister and i had to share an incredibly small room together and it was horrible. To teenagers in one iddy biddy room. You have absolutely no privacy and can do nothing by yourself because they're right there.

 I think if the parents can afford it,teenagers should have their own room.Your room should be your private space where you can do anything you like and sharing a room will NOT give you privacy.

 I think that teens should have their own room if the house is big enough. They need their own privacy and space.

 Your premise says one thing, but your explanation asks the opposite.

I shared a room with my younger sister from the time she was born until I was able to afford to move out. The only time I didn't have to share a room with her was when I worked out of town in the summer and when I went to college. Even then I had to live with others.

As a result of my experience I have to say, if there are enough rooms in the home, a teenager should definitely has his/her own room.

 I think if it is possible for parents to afford a home with enough bedrooms to accomodate all their children then it is a great thing for children to have the responsibility and privacy that their own room allows. I always had my own room and loved it.

 Ideally teenagers should have their own room.
Younger children should be in bed and asleep before a teenager would want to be.
