Should your adult children get a say on the design of their bedroom in YOUR house?

I believe one should always give there children a say, your job is to encourage and support and of course guide them. We let our son arrange his room from the time he could make a point or get his desire across. As long as it was safe we let him express who he was at the time. It did change quite often and i enjoyed watching him grow and change into the man he is today.
