Touch

Today I came across a short video about a group of ladies, young mothers, standing in a queue.  One by one a child, belonging to one of those women was brought in, blindfolded and led from one woman to the other.  The child would feel the hands of the woman, and the face.  The children were of different age groups ranging from 14 to 4.  Each of those children identified their own mother quite instantly.  Most often, the first touch was enough to identify.  Of these some did not even wait to take off their blindfold to confirm, they flung themselves at once at their own mother.  Just a touch was enough to confirm.
