Not a candle! She's my brother's partner, I've only met her a handful of occasions so don't know her well. They live other side of the country. No kids. I find her quite uptight / slightly formal, perfectly nice but the opposite of easy going so I'm not too sure what to get for Christmas when we will be seeing them. I got her a candle last year!
She's quite fit and enjoys outdoors, maths teacher, not very interested in art or music or anything cultural or reading fiction from what I glean.
What's a nice generic gift I can get that's not completely thoughtless?
