Family gatherings that honor particular moments in our lives—weddings, special holidays, and so forth—are often sources of tension when different family members want to "change things up." As a facet of culture and how we learn it, this reminds us that culture is a shared experience. It also reminds us that culture is:.a) static in that remains identical, consistent, and uncontested over time. b) constantly contested, negotiated, and changing. c) genetically inherted. d) completely unique to humans.
