I'm not so sure that is true.
I've decided one of the hardest things about being the youngest and having siblings that are twelve and fourteen years older that you is that said older siblings force her to sit through the things that they enjoy.
Allow me to explain.
Last night, Kim and I were watching TV. Somehow I actually got control of the remote and noticed that Buffy the Vampire Slayer was playing on two different channels. And so I made the comment that Buffy was on a lot.
Kim said, "Is that a TV show or a movie?"
And I said, "Both." And then I launched into a lengthy explanation of why there is both a movie and a TV show.
Kim had never seen either, even though my parents own the movie (on VHS), and so I waxed eloquent on how much Heather and I loved Buffy when we were teenagers.
So then we watched it.
Seriously, I know exactly why we loved that movie.
Kim laughed through the whole thing. She thought it was ridiculous.
It's hard being the youngest. ... And one of the oldest.
