As an introvert, I make plenty of efforts not to be noticed.
Honestly, I prefer to be ignored by the general public because talking to them is a grueling task.
I come off as rude at times, I know, but they are just not aware that at most, I have no idea how to respond so I end up not responding at all.
One of the "I don't know how to respond to that" instances are when people greet me on my birthday. It is just a very awkward encounter for me that I have gone to great length to delete any way people will get notified of my birthday.
I have removed my date of birth from my Facebook page, as an example. I have told my agents that I don't celebrate my birthday and would prefer that they don't broadcast it if they ever knew when.
And then there's Skype. If I can only stop using it, I would; but I use it at work. I don't know who developed Skype but I bet they like to be greeted on their birthday and assumed everyone else in the world likes the attention.
You see, you can't hide your birthday from all your contacts at Skype. Not only can't you hide it. Skype makes it impossible for them to ignore your birthday by notifying them with an automated message. You can't even change it to the wrong date, because if you forgot to change it to a much later date, people will not greet you at the wrong date, which is more embarrassing to both greeter and you.
I hate you, Skype. If I had a choice, I will never use you again.
