Well, I've decided against getting a novelty ashtray for my mum, but she has to be the hardest person to buy for ever.
She:
doesn't do ornaments
doesn't like chocolate
still hasn't used all the smellies sis got her last year
drinks whiskey, but I always buy that for her
likes music, but doesn't really play CDs
likes modern art (but I am scared to buy a print)
id heavily into philosophy and psychology but already has about a million books on the subject.
so any great ideas?
