Whenever I join a full party and all of the DPS are the same DPS. Had a 4 Samurai Memoria Misera one time.

When an AST buffs me with cards exclusively.

When I get chosen for Dance Partner in a Full Party.

Seeing tasteful but sexy glamours on FemRoes.

When people interact, communicate, and talk in duties. Not like non-stop, but at points where communication is easy, like elevators or when there's a long way to run with no combat.
