AIBU on behalf of my sister. i do feel strongly about this one

[floraspread]

in my family there is me and my 2 sisters and my parents.

sister A's dd had her 4th birthday in june, everyone brought her presents apart from sister B.

Sister B had a misscarriage about 2 weeks before SA's dd had her birthday. She forgot about the birthday and didnt get a present

my parents and sister A and her dh had a shouting match with sister B about how (and this bit is true tbh) she forgets everyones birthday and never remembers e.t.c.

But imo Sister B has not done anything wrong, she has now given the child a very expensive trampoline to make up for it. but the main point is she'd just had a misscariage, surely thats something that warrants forgetting your neice's birthday????

I've never had one so i dont know, opinions please?

regardless of whether they knew about the MC (in fact regardless OF the mc) they behaved terribly shouting at her....I would not allow my arents to shout at me like that over an oversight fora childs bday present, nor my siblings, i am after all an adult
!!

Take note - this IS how your parents and sister will treat you in similar circumstanes if you don't ut them straight now!
