andThe Daily Mail reports “vasectomy parties” are a growing trend among childless couples as a way to celebrate the style of living people can have without children. One party invitation asked friends to come celebrate the sterilization procedure in “a house filled with sharp furniture and exposed outlets,” according to The Sun.
Other couples have hosted car or boat “showers” to celebrate the luxury vehicles that couples say they could not have afforded if they had children. Some are adapting baby shower themes and games for the parties, too. A picture from one party showed a jar labeled “Baby Name Suggestions,” only the word “Baby” was crossed out and replaced with “Boat.”
Lord have mercy.The 2012 survey found that 42 percent of students planned to have children, down from 78 percent in 1992.
