She wants to buy him 'something special'. From past experience that means a watch or hip flask of something of that sort. All of which he has already and doesn't need any more of. She asked me for suggestions. The only thing I could think of was that she contributed to an 'experience' that I know he would like rather than a gift. I don't really care is she does or not - it's up to her. But she made a face like a toddler sucking lemons and said 'Well if that's all you can think of.... '
FFS woman! He's your son. Sort it out!
Please note that I buy almost all the presents for her to give my family because she 'can't get to the shops' and she 'can't get the hang of internet shopping'. I am getting a bit fed up with it now.
