My dbro... all today...
First I was taking some tablets and said that I am motivated to always remember to take them because they are costing the NHS lots of money and NICE has just agreed their use in my situation (cancer - hopefully cured but this tablet further reduces the risk of recurrance). He said that he pays his NI and never uses the doctors - basically, he's always well (and in any case he has private for his family etc) - why would he need the doctor given how perfect he is?! (He didn't say that perfect bit but that's how it felt). So he said - and this is word for word - it's effectively me paying for them for you, so you don't need to feel guilty.
Second I was chatting to his son who he brought along. I was making conversation and trying to be nice. DBro said 'stop sucking up to him!' - after which I felt like i couldn't really talk to DNephew any more in case I said the wrong thing.
Third I couldn't find my phone, but turned out to be sitting on it. DBro said 'and so it begins' and when I asked him what he meant, he said alzheimers. To put this into context, we'd that morning been visiting our DM who is dying of alzheimers (seems likely to die very soon) and who I adore. Plus having had chemo, I'm paranoid about chemo brain as I'm back at work and need to be really on it.
At this last comment, his son said 'dad you have no filter', and I said 'yes, he's such a dick'. I've never ever said anything insulting to DBro (I'm v careful of his feelings at all times - I know what he's sensitive about and I'm careful to protect his ego etc). And not ideal to say it in front of his son (16 yo). But I just felt so much sadness inside that it just came out.
