When the boys moved in I try to do something that would make them feel welcomed in my home and make their room feel like it is indeed their room. The something generally involves paint. Painting their rooms is a nice bonding experience.
I asked FS#1 what color he wanted to paint his room, he could paint it any color after all it is just paint. So of course he picked black. Great, calling my bluff, the thought of a total black room was...shudder. So we negotiated on one black wall. Then he asked if he could have his friends sign his walls. I told him that we could work with that. There just so happens to be something called blackboard paint and we can paint an entire wall with it so he and his friends can draw on the wall all you want. In the end, he ended up with a dark grey wall and ceiling, gold walls and centered in the middle of the dark grey wall, one fantastic chalkboard. The color scheme would not be my choice but I have to admit, it worked. I got him those liquid chalk pens that come in brilliant fluorescent colors (and are washable--bonus!) to use on the chalk board. I also told him he was responsible for what his friends wrote on the wall. If I was forced to remove inappropriate writing, I would not be held responsible for what all I erased. He did a great job of policing his friends.
Fast forward to the week before he went to college. FS#1 and I were sitting on his bed staring at his wall. He talked about how much he loved that wall, pointed out favorite or special graffiti how cool his friends thought the wall was and that he was the only one in his posse that had something like this. He also wished he could take the wall to college with him. I told him he could take a picture of is wall for college, but that the wall will still be here for when he comes home.
Now I know that the chalk board was all about marking his territory, staking his claim or whatever. I also know that part of the desire to write on the walls stems from an early developmental age that he did not get to experience. The wall is also tangible representation of permanency. I know all that psycho babble stuff, but what is really important, that wall made me the coolest mom in his posse!
