I'm one of those people that cant remember celebration dates.
In fact, most days I don't even know what date it is.
If u would ask me when is someones birthday I could tell you a couple of dates.
I have memorized the birthday of my mother, father, sister, brother and my boyfriend.
But still I need to set a reminder on my cellphone.
Other celebration dates such is mothers day, most of holidays and other celebration days I don't remember.
Sometimes I am ashamed when I hear people talking and they know when is the date of some celebration day and I don't have a clue.
I guess that is because I don't have a job, and don't go out much so for me every day is a holiday. :)
