Disrespectful? They would have to know that someone considers a particular behavior disrespectful for them to actually be disrespectful. These were houseguests? How would they possibly know what your standards are? Isn't it also the duty of the host to make a guest feel comfortable? Very few households operate exactly the same. What goes at one place may not at another and vice versa. It is up to both parties to try to find a point between where everyone can get along and you come across as being very rigid. It is like being offended. If I hold a door open for a women and she is offended was I being offensive? Only if I somehow knew she would be offended and did it for that purpose. Being disrespectful requires intent. Intent requires knowledge of what the disrespected thinks is disrespectful. Your one man crusade to "educate" others children in what you consider to be the proper way you should be addressed makes you nothing but a bitter old man that probably doesn't get invited back willingly to social events unless your presence is somewhat required. At what point does you forcing your opinion upon someone else's children make you the disrespectful one? Running around with food in your house or jumping on furniture and things that might cause actual damage, yeah I get that, but getting miffed because they are not using your proper title? Lighten up King Francis.
