32 years ago, we provided the cake, the church provided the fellowship hall, and guests provided the potluck. I blame the wedding shows on television for raising expectations too high.
Pair that with no family life to speak of, absentee parents or parents who fail to teach their kids the basics and you wind up with a generation of sickeningly greedy, shallow children who grow up into adults with the attention span of a gnat and the manners of a pig. They wind up knowing only what they see on TV and consider it proper.
