  WE do not know how to make realistic model atmospheres; understand
convection; consider the variation in microturbulent velocity; understand
spectroscopy; have good spectra of the sun or any other star; have energy
distributions for the sun or any other star; know how to determine abundances;
know the abundances of the sun or any other star; have good atomic and
molecular data; One half the lines in the solar spectrum are not identified. We
should get our own house in order before worrying about the neighbors.
