sit-and-sigh

A gathering, function, or just spending fun time with people whom you care about, and who care about you, such as family, friends, boyfriends, girlfriends, etc.
It's just a fun, relaxing time that you spend with those of whom you love, and if you're relaxed and comfortable, you let out a contented sigh.

For Thanksgiving, this year, me and my family had a Thanksgiving sit-and-sigh.
