When I’m writing fiction I forget who I am and what I come from. I slip into utter absorption mode. I love the sense that I’ve become so engaged with the other side, I’ve slightly lost my bearings here. If I’m going from the writing mind-set to picking my kids up from school, I often feel a very short but acute kind of depression, as if I have the bends. Once I’m with them it totally disappears, and I feel happy again. Sometimes I forget I have children, which is very strange. I feel guilty about it, as if my inattention will cause something to happen to them, even when I’m not responsible for them.
