Don't tell me that when ATC tells you: "Traffic, 10 o'clock, passing left to right, climbing to FL360, 1000 feet below you, Airbus 320", you read back the entire message?
I assume that's for me Bus man so no, I don't read back the entire message. I respond with my call sign to indicate I have heard and understood the message. Roger is a redundant statement . Sorry for the drift
