Those overalls I covet

I wonder if I have coiled up, like a millipede sensing threat.  Vulnerable bits center, shelled bits facing the world.  I have a hard exterior at times.  I don't think I braced for menacing danger, but I also know I have pulled away, pulled in, tucked, blocked ... so deep breath - time to get those many legs back on the ground and explore.
The spiral is an ever alluring image for me - circles upon circles; lines, cycles, movement stillness all juxtaposed into one image.
