it 's offense you maybe ca n't live with , because it opens up a crack inside your thinking , and if you look down into it you see there are live things down there , and they have little yellow eyes that do n't blink , and there 's a stink down in that dark , and after awhile you think maybe there 's a whole other universe down there , a universe where a square moon rises in the sky , and the stars laugh in cold voices , and some of the triangles have four sides , and some have five , and some of them have five raised to the fifth power of sides .
