A lovely work colleague brings me a pastry every Friday, along with one for herself .
I feel I should reciprocate but I didn't start this and therefore don't think I should feel pressured to do so..
I've tried thanking her and saying I'm trying to lose weight so please don't bring then in future but she carries on.
Should I accept gracefully ( the pastries are lovely) and continue not to buy for her? Or do I have to reciprocate despite feeling disgruntled at having to spend the money?
