So I would take the whole story of the movie day with a grain of salt. I'm not saying it didn't happen at all, but probably not quite so dramatically.
I could see this happening this dramatically because *my* mom tried to do a version of this to my sister and me (and Mom really isn't a mean person so I think this situation was, actually, unintentional).
Mom came up to YS and me and said, "Hey, let's go see a movie later; that would be fun!" YS and I got excited because, well, our family never went to the movies at that point (not because we couldn't afford it, I think, but because we weren't small children anymore so piling us all into one vehicle to go to the drive-ins wasn't going to work anymore and my parents NEVER took us to a regular movie theater). Anyway, YS never did the work for anything so I took it upon myself to peruse the movie listings and figure out which movie we wanted to see and when (and I did this all in front of Mom). YS and I finally determined we wanted to see
Back to the Future, and I told Mom. As it got later and later, I said, "Hey, Mom, when are we going to the movies?" and Mom replies, "Oh, I don't feel like going now."

I. WAS. FURIOUS. I thought that was the meanest thing ever. I couldn't believe she'd jerk our chains around like that....and my 14-15 year old self let Mom have it. Yup, Mom got a "severe" tongue-lashing for suggesting something fun for us to go do with her and letting us happily go about planning for it only to never have had any intention of executing the plan. Oh, I was so angry with her.
Anyway, I guess my words really got through because, a few minutes later, Mom changed her mind and took us to see the movie (like I said, I don't think she meant to do something so mean; I really think she changed her mind and was just super clueless how mean it was to do that).
