There's something about walls

I have a sudden rush of adrenaline when I paint walls..the mediums vary from permanent markers to photo inks, crayons, fabric paint to anything and everything that is lying around the house.
I have been lucky with landlords who have let me decorate their walls... but there is one feeling I loathe the  most.... leaving them behind..sometimes I wish I could break that section of the wall and take it away with me. I decide everytime that I will paint on something I can carry.. but eventually I end up painting on the walls...I feel like they were meant to be there...kind of like the feel and spirit of the house... here's to more paintings on the walls...
