Ninjakitty's sister + Equestria girls

So earlier today, I finally got sick of not knowing and watched Equestria girls on youtube, despite the quality being... well... Video-taped quality.

My sister, who was a little girl in previous generations, and was the type that wanted all the pony toys, came downstairs and sat behind me and watched the entire movie over my shoulder. I had to explain who the characters were, why I laughed at background peoples, and what was going on.

When it was over she stood up and went to watch tv, saying nothing about the movie.
An hour ago she said "I ship Flashlight." (flash sentry and twilight sparkle)
What do I do about this...
