Your inner child is not a psychological concept.  Your inner child is
real.  You simply have to find it.  The easiest way is to have it paged
at Sears.  Go to the Service Desk and have them announce over the
loudspeaker, "We have a lost inner child at the Service Desk named (your
name).  Will the owner please claim it?"  Hearing you inner child
announced loudly over the P.A. will melt the barriers you've spent years
erecting between the two of you.  Once you've reunited, go visit the toy
department.  You won't believe the cool stuff they have nowadays.
