Good evening, everyone! As part of the parent committee for my older son's class (9th grade), I'm organizing the graduation party. The parent committee from the parallel class and I agreed to split some costs. For decorations, we decided to just pool our money. But regarding gifts for the teachers and staff, I suggested we divide the cost based on the number of people and buy identical sets ourselves (flowers, notebooks, candies, chocolates). However, the other parent committee wants to just collect money for it. I don't understand the point of collecting money like that... and how to report back to the parents afterwards.
