Something fishy here as confirmed by her last post. That is the typical inappropriate and rude actions of many active witnesses who post on here.
Although Jehovahs-Witness is clearly shown at the top of every forum page, the extreme misspelling 'jahovas witness' which I believe is only to imply she doesn't know much about JWs. She then states she had been attending the KH & BS. Someone with even a few 'studies' with JWs would have a basic understanding of their 'beliefs'. NO birthday celebrations, Christmas and blood are usually well known to non witnesses with even the most basic knowledge of JWs and especially someone with a close family member who has been an active witness for any length of time.
Most anyone who would have questions on their mother's decision to not help out because they mentioned a 'birthday treat', would first ask an explanation from their mother directly, not a bunch of strangers on an internet forum.
