Doesn't seeing things (like numbers and weekdays) as other things (like genders and colors) count as an disorder of sort? Anyway, to me it's quite weird so many people seems to think this way. Numbers to me is just numbers. Sorry.
this sort of thinking is probably a form of synesthesia or minor autism but really quite common. I didnt even know I attributed genders to numbers but knew I attributed colors. I also attribute colors to letters.
gosh, I thought it's just me! I also make genders for numbers. 1 middle-aged male 2 middle-aged female 3 old male 4 old female 5 young male 6 old female 7 about 30 yo male 8 about 40 yo female 9 old female 0 sometimes male, sometimes female
