I act like I'm "normal" around my family and friends. LOL Well, as close to normal as I ever get....*ahem* To tell you the truth, the only thing I have to remember not to do in public is refer to him as "Daddy." I'm sure that would get a few horrified looks at my mom's house, but in public, I don't think many would notice it since he's technically old enough to be my daddy, unless we kissed or something after they heard me....LMAO! Most of my friends know what I'm into, so they don't bat an eye when I let the "D" word slip. We don't really have any protocols to speak of, so it isn't hard to act naturally around other people. If he asks me to do something or not do something in public, he does it quietly.
I actually had a similar situation come up, and I didn't really know how to respond. My dom and I were having a disagreement. I was out at a bar with my best friend when he text messaged me. It was to let me know that I had an email in response to a letter I'd sent him earlier that day. I began to worry about what the email might say, etc., and began to cry. My friend became angry and told me to turn off the damn phone. She said, "I know you like to play games and call him "Daddy," but he's NOT your daddy! You don't have to listen to him! You came out to have a good time, and he's not going to ruin it!" I just gave her a bewildered stare. I think I told her I knew I didn't have to but that I wanted to. I didn't turn off the phone. I continued texting. What she didn't know is that he wasn't trying to ruin anything. I wanted to go home right then and check my email instead of partying with her, but he assured me that it could wait and that I should stay and have fun. I told her that everything was fine, but I didn't go into any detailed defense of my actions because a noisy bar isn't a place you can really talk. My advice is to not do anything obvious that would draw attention, but if anyone asks, depending on who they are, either tell them to mind their own business or tell them everything is fine. You don't have to go into some long explanation of what is nobody's business but yours.
