Do your research, respect the ladies and you will be respected. If you conduct yourself in this community, like you conduct yourself in your professional and private personal life you will not run into such problems.
Everyone makes mistakes, says the wrong thing, makes appointments and has to reschedule, misinterprets others communications and/or emotions, and yes at time you will get called out.
I consider myself, and others share this feeling (I say this not out of hubris, but plain truth), as a gentleman all of the time. However, I still get corrected, told no, and sometimes catch an "ass chewing" over something I have done, have failed to do, and/or possibly said.
This is life, not everyone is going to get along like some idealistic utopia. Suck up your pride, apologize or acknowledge your part in it, correct the situation you are called out on by somehow remedying it and/or not doing it again, put on your big boy pants, don't get butt hurt, move on, and I promise things will get better! Even if the person you have had conflict with, may not be your "BFF" after the situation, at least you know you have taken the high road.
