I don’t particularly like celebrating birthdays or holidays so I definitely do not expect anyone to remember. I also avoid telling my birthday whenever I can evading as I can. That being said I throw peoples birthday into my cal as I discover them so I can be congnizant of them since most people do celebrate that stuff. If you want to impress me though get me a really relevant gift out of the blue that you got for free, made, or was just a steal of a deal. or a handmedown. don’t be like seinfeld though and lie to me on how cheap you got the thing as the experience should be authentic.
