AITA for not knowing traditions? TW: death mentioned
I'll be honest, I'm not entirely well-versed with a lot of the traditional Filipino customs due to growing up in Canada. Most of the traditions that were taught or at least passed down were about New Years and Christmas (12 round fruits, hanging grapes upon the upper doorframe).
For some context, I had this plan of wearing a red dress to an upcoming concert and I thought that it'd be nice to dye my hair red just to coordinate with my outfit. Unfortunately, my grandma had passed away unexpectedly, prompting for most of my family to leave and go back home (I couldn't due to financial constraints and my job). Even if I wasn't able to attend the ceremony and be there for my grandma, I did the best I could from across the sea and helped arrange pictures for the slideshow they wanted to put together.
However after the burial, I video called my mother to check up on her to see how she was doing. And when she saw my hair, she shouted at due to my hair being red. There is a tradition that I didn't know about until today-- that wearing red symbolizes that you are 'happy' about the person being dead. I insisted it was just for the concert and nothing more, and my mother told me that "its tradition to avoid wearing red for the entire year after someone passes", and that she had just found out about it the day before. I explained that I couldn't have anticipated my grandma passing... And that if I had known about the tradition, I would've dyed my hair a different colour out of respect for my grandmother because I loved her dearly. Now I'm worried that my grandma watching from above or my other relatives will think I'm happy about her passing.
Am I the asshole for not knowing about it?
