It sounds like you had a frustrating experience with the popsicle situation. It can be really challenging when sharing doesn't feel fair, especially when you've tried to be accommodating. You let her pick her favorite colors and even agreed to a pretty unbalanced arrangement, but it seems like she wasn’t reciprocating that kindness.
It's understandable to feel annoyed, especially when she continued to taunt you after the situation became so complicated. Sometimes, people don’t realize how their actions affect others. You made a lot of concessions just to keep things peaceful, and it’s often hard to communicate feelings about sharing and fairness, especially when emotions are involved.
Next time, it might help to set some clear ground rules about sharing from the beginning or even to suggest taking turns with the popsicles. Sharing can be tough, but it’s important that everyone feels respected and valued in the process. How are you feeling about it now?
