the first is be aware that names have power. give yourself a nickname or give no name at all.
the second is do not accept anything edible from a faery. to eat from the lands of fae is to lock yourself from the land of mortals.
the third is regarding information. if a faery gives you information, do not thank them. you may say you appreciate their assistance, but thanking is tantamount to admitting a debt owed.
the fourth is about accepting gifts. be very cautious when doing so. many gifts will have unforeseen side effects. if a gift is offered, accept it, but if you do not trust the one who offered it, do not hesitate to destroy it. salt water is always a good cleanser.
the fifth is how to speak without offense. most fae are very old. this means propriety is very important. grudges can be held for centuries when you live millenia. if you do not wish to do something, the way you refuse is critical. be polite. anything less may land you in hot water.
Sixth. Say what you mean, nothing more, nothing less. The fae tend to be very literal. Pay attention to exactly what they say and do not assume it means what you think it does.
