Input: Hey AITA! This isnt a new situation that just came up, rather one that happened a few weeks ago. Idky i thought of it randomly, but wanted to see how youd all weigh in since Im on the fence.

Another warning, this isnt about me directly, but rather something that happened  between my mom and sister. Mom is M, sister is S. Mom is mid 40s, sister is mid-early 20s.

M was informed by her mother (my grandmother) that their live-in-friend (lived together, im unclear on their relationship since--for at least 20 some years--gma lived on the bottom floor and her friend lived on top but shed make him tea, cook the odd time and hed cook for her, hed drive her places, theyd smoke together, watch tv together, etc) had passed due to lung cancer. M passed along her condolences and that was that. Call done. M told S what had happened and S was upset, asked about the funeral and M told her that if she wanted to go, then she could call Gma herself and get the details as she, M, did not have them since she did not plan on attending.

S gets mad but leaves and gets the details for the funeral. S tells M and asks her if shell go now and, surprise surprise, M's decision hadnt changed in 36hrs (day and a bit idk the exact time frame) and said no. S gets mad and offended and asks if M will go to support her, and M again said no.

S and I knew the guy who passed away. Hed been very kind to us but 1, we havent seen him since we were 12 (so about 10 years ago). 2, when we did see him, it was once a year. Yes, he was nice and cool and awesome but there wasnt much to the bond (S confided in me that she was sad but not like devastated or anything and felt like she had to go because she knew him).

On the other hand, M did NOT know the guy who passed. She saw him even less than we did (2hrs top a year when she dropped us off to spend a week with him and Gma). He came into her moms (Gmas) life, AFTER her dad left Gma. M also does not get along with her side of the family. At all. She especially is not fond of her brother who, of course, was also giving M shit for not going along with his wife apparently. M also especially doesnt like her mother (Gma) who was pretty damn verbally abusive to M when growing up. I do not blame M for not wanting to go in the slightest. 

S is.... tunnel visioned in things and just got more and more POed with M. I understand the need for support but like, if S needed it then she also could have asked me (early 20s,have comforted her at many a-funeral before) but she never did.

Tldr; S is claiming she need moral support at a funeral to a gentleman we kinda know but hadnt spoken to in close to a decade. She demands that support from our mother, but mother doesnt know the gentleman and doesnt like her family and is refusing to go.

So, is my mother TA for not wanting to attend the funeral?
