I think it was quite stressful since it's not just one, it's two birthday parties. And apparently time was not your best ally that day, there are definitely times where we get so complicated and just improvise.

That children share with others is quite important for their relationship with other children, playing and having fun. I imagine that the place where the second party was in the "middle of nowhere" made things difficult for him.

Imagine if you had bought the toys that same day too! Total chaos.
