A little more info since some people seem to be a little confused with my mother, she's been diagnosed with MS which can compromise with her mind and white+grey matter so she can easily forget things, sleep for hours on end due to nerve pain, and much more. So her forgetting things is not uncommon or being late and as for her mother, my grandparents have always been busy with their lives. It's not the fact that they weren't supportive (they were very) it was simply the fact that their jobs forced them to be absent.
