Er, never.

I conjecture that the next person curses

Nope, I've got three older brothers that will stop me if I even try.

I conjecture the next person is the baby of the family!

Yes! I hate it.

I conjecture that the next person is very careful and catious about everything

I'm not very cautious, but I'm certainly more than all of my brothers.

I conjecture the next person likes soup a bunch!

Lentil soup, home-cooked soup, chicken soup, creamy potato soup, tomato soup, I love it all.

I conjecture that the next person wishes that they had a sister(I sure do)

I've got two sisters! One of them is mental and the other is really cool! Even though she's mental, you could never get me give her up!

I conjecture the next person has run all the way up from Slytherin to the top of the Astronomy tower!

Merlin, Colin, what do you take me for? I'd pass out before getting to the second floor!

I conjecture the next person values physical abilities over magical ones

Always. It's not like we can do magic over summer. Besides, my brothers can't do magic.

I conjecture the next person doesn't like being around little kids.

Come on, Loops!!! It's only 683, 499 steps from bottom to top! And twice as many going back down, so we should be thankful!

I don't mind little kids. They're fun to practice spells on anyway!

I conjecture the next person knows a part Goblin or Giant!

I've landed myself in a detention with a part giant recently, so I suspect we'll get to know each other pretty well soon!

Colin not all of us have your stamina. Or deathwish.

I conjecture the next person would side with the Goblins in a modern rebellion.
