The primary useful purpose of the tooth-fairy myth is probably to give children a small reward and something to look forward to when they lose a tooth, a process which they might otherwise find worrisome. It is fun for both parent and child. It also gives children a reason to give up a part of themselves that they may have grown attached to. ; h: ~: c+ c9 p- x6 H7 l* D! @6 `; x % r- T' y5 H% L8 Z; P% b- B, W!
