Acting 'peevishly' means behaving in an easily irritated, annoyed, or complaining manner. It suggests a tendency to be grumpy and difficult to please. It's not just about being unhappy, but also about expressing that unhappiness in a petty and irritable way. Think of a toddler throwing a tantrum or a friend who constantly complains about minor inconveniences. Peevish behavior can be draining and off-putting. It's about letting small annoyances control your mood.
