Now I feel like an idiot for overreacting. Circumstances beyond our control meant that the trip I was looking forward to wound up getting cancelled for nothing.
We were all frustrated over it, enough so that, somehow, we convinced fate to let us resume that one, just at a later time.
So we went to my brother and sister's place, since at that point, the reason that trip got cancelled was basically...cancelled itself.
At least it was fun hanging with them. They didn't seem angry, either, and I got my Sonic and Mega Man amiibos...while being jealous of their own collection. They have Lucario, a Meta Knight, Wii Fit Trainer, Villager, Shulk, Pit, and they're getting King Dedede in the mail.
Sounds confusing? I'm still trying to make sense of it myself!
