So, because you have an issue with hand-shaking, you think that martial artists, in a Western society, should maybe bow to each other instead, as that's what's done in Asian cultures, without even understanding why it's done there? Or why hand-shaking is done in Western culture? And without addressing the idea of how on earth martial artists are supposed to recognise each other in order to determine whether they bow or shake hands?
Can you see the issues with that?
Completely irrelevant. It really doesn't matter what kind of a day you've had, it doesn't matter how you feel about comments on your birthday, it doesn't matter what day it is, or what "names" you get as a result (I'd be willing to bet that you don't actually get called a name, although I can guess that a name is associated with the date, and it's referenced as a form of joke… and I'd suggest you learn to distinguish between those two occurrences), it doesn't matter what you think about how things should be either. The simple fact is that, while you are right that you can be "firm" about lines you don't want crossed, there are ways to do that that are socially acceptable, and ways that aren't… you, so far in both threads on this type of encounter (here and the hand-shaking one) have shown no ability to determine what they are. That's what you need to understand… frankly, if you behave in real life anywhere close to the way you present yourself here, you will be very socially isolated, and have a miserable life, allowing everyone and everything around you to frustrate and offend you.
That's why I'm saying you need help. You need to learn how to operate socially… right now, you just appear as if you'd come across as a rather self-centred jerk… which is of no benefit to you whatsoever.
Here's a suggestion. Let's throw a random date up there, that might give a name associated… let's say this hypothetical birthday is the 25th December… and people ask if your name is Jesus, or maybe Santa… maybe Kris Kringle… Instead of getting frustrated, acknowledge that, when someone learns the date, they're going to have some comment… it's a natural occurrence (if you want to know the psychology behind it, essentially they're making a connection between the date and their experiences… as the date is an unknown at the beginning, the connection also comes up as a surprise… which is why they offer their comment… in simple terms, they're just responding to what is to them new information)… so you might want to try heading it off… "My birthday? 25th December… my folks considered calling me Jesus, but with the last name "Jones", it was just a bit 80's…", "Sure, my birthday is December the 25th… I get double presents… it's great!", "December 25th. Now it's your turn… are you going the Jesus or Santa route? We'll see if you've got one I haven't heard yet!" (remember to be smiling as you say these!). Of course, you could simply acknowledge their comment in order to move on… just know that it's going to be said, and frankly, deal with it… going back to it to say how you don't want any focus is really just bringing focus back to it, you know… which really just says that it is something you want to bring attention to (as does this entire thread, bluntly, despite your protestations)… so, if you really don't want any attention on it, move past as quickly as possible.
"My birthday is December 25th."
"Really? Were you delivered in a hospital, or did Santa just bring you down the chimney?"
"Ha, you know, I never asked… anyway, what I need is…"
Does that make sense?
