OK this is a real challenge for you:
My parents are typical Yorkshire folk - genuinely do not like spending money or having money spent on them! They are very ecologically minded and don't like stuff for the sake of it, as it inevitably ends up as landfill. As an added difficulty my dad is dying and fairly soon they or (more probably) just my mum really need to massively downsize and move from a huge 5-bed house to something manageable, (ie dump a lot of 'stuff'). I bought my dad flowers for his birthday this week, so can't do that. Oh, my dad is basically not eating either - did I mention that?
(Are you still with me?) So with all this in mind I've bought lots of luxury food stuff, and packed it up into a nice hamper. With a thought that maybe the special foods will tempt my dad to eat a little bit.
But I feel this isn't enough, and I need to do something more lasting. But I've no idea what. Any suggestions?
Oh also, my dad has set this anniversary up as a real psychological milestone I think - after which he will give up - so I am also a bit wary that any 'lasting' gifts are ultimately going to be seen as memorials of his parting.
Sorry - this is a bit grim and maudlin, isn't it?
