Our society has become that way.   How many folks go out on a porch.   Children stay inside and get on their tablets and Ipods.   We do not introduce ourselves to each other...let alone asking for a cup of sugar or to borrow the hammer.   We don't help each other.   They have conditioned us over a period of decades to ignore our neighbors.   It started with the radio then the TV set then the  computer and tablet.  Before you knew it we were living inside instead  of getting the fresh outdoor sun.   SAD.
