Resonances

Wandering around school as usual, reading the notices and popping my head into the classrooms. I have some homework to do but I can't remember what it is - something about an essay. Is it in Irish or French or English? I know exactly what I will write about but not in what language or for what class. There are instructions on the blackboards of various classrooms but nothing seems quite right. All of the pupils are wandering around like me; there don't seem to be any teachers.

I got a letter from an old friend telling me about how he has felt about me over the years. He is talking from a perspective that looks back over our whole time together and says that he has always only wanted to maintain a connection between us, and that twice now I have broken it and hurt both of us. It seems like he is talking in a way that someone far wiser than me would, but I don't know if I should take it that way or only as an expression of his perspective. I think I try to explain myself; I can't remember. I only remember stumbling up in the darkness of a bedroom of a strange house and making my way to the bathroom without turning the lights on. While I piss I see the dim reflection of my head in the mirror; it looks like my head is shaved.

I am explaining to someone about how to design a structure like the Eiffel Tower so that it doesn't get destroyed by the wind. Wind of the right frequency can induce a resonance in a structure like that which can tear it apart if it goes on long enough; you have to add extra strength or weight at certain points in the structure to destroy the harmonics.
