We can all say similar things to a person, but depending on who it is and how they know you, that can play on allot of different levels. If my wife says I need to lose some weight, my reaction might come from an entirely different place because we've had past conversations and its understood when its brought up, its because she cares and there is a concern. If my brother says I could stand to lose weight, my response with him might be more reactionary because he could have a tendency to take jabs, thereby making me interpret the delivery differently.

So if I were in your shoes and see discrepancies on that level, I might ask myself is that person expecting me to give them more consideration because I know them well enough NOT to say those things? I think when you get to know someone pretty well, somewhere in that hand shake is an understanding of how you know each other. And with that understanding, there's places they know you can hurt them that others would not know, so they will interpret those remarks from a different perspective. Does that make sense?
