My daughter got married five years ago. She had a great wedding reception at a lovely venue with good food and good music. Most of the so-called friends that attended did not give the couple a wedding gift. I am old school and I personally believe that was extremely bad form.
Obviously, this was not a Goodfellows wedding!
I'm with you. I've seen such crass behavior at the weddings of so-called educated people in the past 20 years or so. It's sad. Don't get me started on the creative "own vows" and "dancing down the aisles on YouTube" antics in churches, and the boozy receptions.
People have lost all sense of it being a rite of passage to adult responsibility, honoring God by sanctifying an intimate partnership, a joining of two lives, preparing stability for future children, or expressing solidarity with the elders who nurtured them to this point. It's become about impressing their friends, not continuity with religion or their families.
