Quit talking to me in that condescending tone! You always treat me like a child – ugh!.
Those who thought they were honoring me by condescending to address a few words to me. --F. W. Robinson.
Can they think me so broken, so debased / With corporal servitude, that my mind ever / Will condescend to such absurd commands? --Milton.
Don’t condescend to me! I know this as well as you, if not better.
