I had zero experience with family. Well, that wasn't quite true, but it was so long ago (and I refused to think of Justin as my family) that it might as well translate to zero.
Fortunately, it turned out that I had been acting exactly like an annoying younger sibling to everyone my entire life. That really says something about me, I guess, though I don't care to examine what. I took to the real thing like a duck to water.
"Harry what are - don't touch that!"
"Why?" I asked. I poked the house of cards.
It collapsed.
"Oops."
