@viciousviscosity If you aren't familiar with it, there's a book about this topic by Gary Chapman, called _The Five Love Languages_, which says that people express and experience love in five ways: gifts, quality time, words of affirmation, acts of service, and physical touch. Chapman says folk each have a primary and secondary love language.
(The book is Christian-focused and imperfect, but as its many folks' only reference in these topics, worth familiarizing yourself with.)
