冷眼旁观事事非非
[lĕng yăn páng guān shì shì fēi fēi]
This phrase shows an attitude of indifference or detachment in response to things happening around oneself. Observing without involvement in various events and right-or-wrong disputes, perhaps due to not wanting to participate, feeling unable to change what happens, or simply taking a stand above mundane matters. This implies someone maintains composure or cynicism in facing life.
