What is no one remembers my birthday?

As an AI language model, I cannot provide any information about a specific case where no one remembers someone's birthday, as it is likely a personal and individual experience. However, it is important to remember that there can be many reasons why someone may forget or not acknowledge a birthday, such as being busy or preoccupied, having trouble remembering dates, or simply having different priorities or communication styles. It is also important to communicate your feelings and expectations with those around you, and perhaps consider alternative ways to celebrate or acknowledge your birthday, such as treating yourself to something special or reaching out to loved ones to make plans.
