Growing up in upstate NY we lived on about ten acres which were bounded on the south by a creek (the Poestenkill - in case TK ever comes back ).
Along the north bank of the creek, a little ways downstream from a spillway some previous owner had built, was a big concave boulder, set low but still high enough to stay dry most of the time.
I used to sit in that bowl-shaped depression - there was another rock a little ways out that I could put my feet on. Once in a while I brought a notebook and a pencil and worked on an assignment, which led to me dubbing it "Homework Rock".
Sitting on that rock, in the afternoon light after school, listening to the creek go by...... so peaceful. Sure, it was a rock, but it fit me well - it was comfortable.
We moved away 22 years ago but I still remember so much of that place, so well. I miss the whole place, but that rock will always be special.
