Does rank play a part in how you view individuals after you have left the service?

Whether it be on social media or in person at the local Veteran Service Organization (VSO), does the rank that you left the service with and the ranks that other veterans left the service with play into how you view, associate with, or speak to other veterans? The highest rank that I ever had was Sergeant and I still find that I address those that I know were officers as "sir" or "ma'am". (I also address all generations of older veterans as "sir" or "ma'am".) I still hold a certain level of respect for all those who attained a rank higher than I did, but I do speak to them as if we could have been old friends. I consider us all on almost a completely even field after leaving the service. Does anyone believe any different?
