Once when very young, in either 1st grade or maybe even kindergarten, i was with neighborhood kids playing doctor in the bushes between the houses. They were very thick and covered a large area and had sort of small paths in between them that were suitable for kids, but not grownups. But I didn't really like it there - too many icky bugs and insects and dead leaves and spider webs and all that outdoor stuff. I just watched the goings-on but was probably very turned on. One of the kids must have ratted or blabbed because one of the parents came to our house with a face and demeanor like a thunderstorm and talked to my mother. I was scared I was going to catch it, but oddly my mother never mentioned it to me. I suppose she figured just kids stuff.
But a favorite place was in the attic my grandmother's old 19th century urban house in Belgium. It must have been on the 5th floor, way up and away from the rest of the rooms that were in use. It was dusty with old things stored along the walls and very hot in the summer. The sounds of the city streets were also more muted and far away though church bells rang out even more clearly so high up. There were also small partitions built against the sloping walls in which to slide things for storage. A somewhat younger male cousin of mine and a somewhat older daughter of my grandmother's tenant used to go up there to play when I was in 4th or 5th grade and get up to many sorts of games - playing house, going to the store and also of course playing doctor now and then. The girl was a sort of take-charge personality while my younger cousin was more compliant.I liked to watch mainly - latent voyeur already ... ha ha
I cherish the memories of being warm and wearing very little or nothing much and oddly enough the dusty and seemingly remote atmosphere of the attic. I will still sometimes get a pleasurable chill when going into an attic or abandoned building or room.
