Yes, your daughter has had the quintessential American child experience which is most likely going to underscored by taking place in a western-flavored cis heterosexual context. What I’m saying is that it’s all relative. Your daughter’s relationship experience will be different than an ancient Egyptian, or a Native American, or a Viking. There is nothing “natural” about the way we currently partake in relationships as Americans. And my point is that it is weird to assert “My child is so in love!” Let them express things on their own. Give them that freedom.
