My grandmother is 90 and generally very well for her age although she suffers with a few aches and pains and her mobility is reducing.
GM is seen by a physio, podiatrist and sometimes has a few extra appointments too with the nurse or the GP.
GM has children and grandchildren who all work full/part-time with the exception of one daughter and her husband who are both retired.
All family members are in a group chat, set up to arrange who can take GM to the appointments as we try and take it in turns where possible and consolidate as many appointments together as we can.
GM's daughter, my aunt and her husband, despite being the only retired members of the family, have on only one occasion taken GM to an appointment.
Sometimes, when we arrive to collect GM or drop her home, they are sat in her house!
Some of us have babies, and my aunt will see the request for help in the group chat, ignore it and wait for someone else to volunteer, including her own children who also have babies!
AIBU to think that this is actually taking the piss! If we say anything or ask her directly face to face to take GM to a certain appointment, she cries and makes a fuss and just says she wishes she could help more but she can and chooses not too!! SO ANNOYING!!
