"A lot of people would rather tour sewers than visit their cousins"

This quote by Jane Howard is an amusing way of expressing the concept that many individuals would rather do something unpleasant than hang around with their loved ones. It indicates that people find spending quality time with their cousins to be so unpleasant that they would rather do something as undesirable as exploring drains. This could be due to the fact that of the awkwardness of household events, the absence of typical interests, or the feeling of obligation to hang out with member of the family. It could also be because of the potential for dispute or the feeling of being judged by member of the family. Whatever the reason, this quote suggests that lots of people would rather do something unpleasant than hang around with their cousins.
