Quality time
Quality time is a sociology expression referring to a proactive interaction between individuals, set aside for paying undivided attention, usually to express love or accomplish a shared goal.
Sometimes abbreviated QT, it is an informal reference to time spent with close family, partners, or friends that is in some way important, special, productive or profitable to one or everyone involved. Having conversations, solving jigsaw puzzles, collaborating on projects, and conversing during road trips can be examples of quality time. It may also refer to the effective use of time in educational settings, or time spent alone performing a favorite activity (i.e., self-care).
In his 1992 book, Baptist pastor and Relationship counselor Gary Chapman suggests that quality time is one of five "Love Languages" which are used (more or less, preferentially, by a given individual) to express love and gratitude for another.
