adjective
stolid
STAH-lid/ˈstɑːlɪd/
Calm and showing little emotion or excitement.
The young woman stays stolid as her companion delights in the gift.

Etymology
Latin stolidus meant, properly, “unmovable,” as well as dull or insensible. That lack of movement carries into emotional impassiveness: a stolid person shows little outward response.
In context
