silently showing dislike and lack of cheerfulness
dark and gloomy
"a dark scowl"
"the proverbially dour New England Puritan"
"a glum, hopeless shrug"
"he sat in moody silence"
"a morose and unsociable manner"
"a saturnine, almost misanthropic young genius"
"a sour temper"
"a sullen crowd"
"a heavy sky"
In the car..there had been long, almost sullen silences.
