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. 8 O2 W9 E4 {7 n! s' o- y) _9 O% ~
Some believe that other useful purposes include giving children a sense of faith in things unseen, believing in the incorporeal, and helping them understand the difference between the real and the imaginary.& l: `/ c, b" T0 D9 _& k g9 U
