J., I don't know if there is an age limit as such, but I have to express something that's bothered me since I was a little girl. I shared a bedroom with my baby brother when we were little & had a small bungelow home. My father built me a bedroom of my very own upstairs when I was about 7 years old. I was so excited, but my Mom was dead against me staying in it. She was/is a housecleaning freak & she didn't like us stepping on her precious area rugs & messing things up. Anyway, she made me stay with my brother until I was in junior high & I was so embarassed. I'm not saying that you would do something like that, but it really made a lasting impression on me that I can't live down & it was all because she didn't want a mess. We were the cleanest kids in the neighborhood. We could never have kids/friends in the house because she wouldn't let them, but also, we were afraid someone would find out that we had to sleep in the same room. Thank goodness they were twin beds. It's just a really bad memory. Just wanted & NEEDED to share that.
