I Am Furniture

At what point in my life will I stop looking like a chair to my children? If I'm sitting in a room and they either enter or are already in the same room, they WILL, without question, be using me as their chair, sometimes both at once. I'm starting to feel like a mall Santa Claus here. Actually, now that I think about it, I don't even need to be sitting, I can be laying down and they will still sit on my belly or chest, deriving great joy at the strained sound I make when they plunk down on me as hard as they can. Is it my clothes? Do I dress like furniture?!
