I apologise in advance for ranting but oh man am I annoyed. So my dh’s mum has terminal cancer and doesn’t have long left. We visited the other day and she said that she’d love to sit out in her garden but for her to do this we need a wheelchair. DH and FIL phoned around the relevant services to see if we could source one but unfortunately there were none available in their area. Then it occurred to me that my Nan has a wheelchair that she rarely uses and she isn’t using it at all right now as she is in hospital. So I thought I’d phone DM and ask her if I could borrow the wheelchair for a few hours. My DM is known for being awkward at times so it’s rare I ask her for anything but on this occasion I didn’t think for a second she would say no to me borrowing the wheelchair but she did. Well actually she didn’t say no directly as she never does this instead she did what she always does and dances around the question making all sorts of excuses, one being that my aunt’s husbands mother gave my Nan the wheelchair. My Aunt’s husbands mother is dead! Then she said well it’s the only wheelchair your nan has got. What has that got to do with it? I have on occasion borrowed things from my parents and never once have I broken them so what is the issue? I have adhd and can fly off the handle sometimes but on this occasion I said oh ok as I was so tired and couldn’t be bothered to argue with my DM but I got off the phone and I wish I’d called her out on the way she behaved. I fuming! Like i said I have adhd so I tend to over think things but on this occasion I don’t think I’m wrong to be mad. I suspect DM could be on the spectrum like me my son and possibly my dh is too but the difference is we all have hearts or gold and we would help someone in need if it was in our power to do so. AIBU?
