Imagine you are:
A nine year old boy - you have lots of toys already, not a mad keen reader, and would be very disappointed to receive toys - is it okay to just give you a tenner and a box of chocolates/selection box?
A forty something woman; very stylish - for around £15 what would you like?
A forty something woman who's quite practical and down to earth - ideas for around a tenner?
A 19 year old tomboy/student - likes beer, painting, pasta and hoodies, but I've already bought the beer, paint and hoodie!
