I recently went away for the weekend with a group of friends. One of them had organised and bought the food shop for everybody. I left before the rest of them and as I was packing she came in and asked me to give her the amount I owed towards the food. There had been some email exchange before the trip but no clear instruction how much it would be or how she wanted people to pay. I basically felt cornered to pay before I left. Now I feel offended that she thought she had to do that. As I left early I don't know how it was handled with the others. Am I being overly sensitive? I was annoyed at myself for forgetting to offer before she asked me but now I feel she was a bit too strong in asking.
