I have this issue every year. She's not into fashion etc so a nice scarf is out. She's not a foodie. She doesn't have any hobbies apart from Sudoku and her mum has already bought her a huge stack of sudoku books for christmas.
She's a teacher and lives in London during term time but comes back home to her family during the holidays however she's retiring soon. Last year I got her a World at War boxset and the first series of Downton Abbey on DVD.
This year, we have a DS and we're skint so the budget can't really stretch beyond 10-15. Does anyone have absolutely any ideas?!
