It isn't specifically meant for aspies but it tells you what NT's look for when they judge people. It is meant for girls but a lot of these tips apply to guys. If you ignore the school setting I am sure you can apply a lot of these tips for work, social gatherings etc.
Good luck everybody, I hope it helps.
