Have you ever had a fight with your sibling over who should get to keep something? In a small village a long time ago, Queen Ethiconia had to settle a dispute between three siblings fighting over a musical instrument they all want and all think they deserve: a wooden recorder.

As a kid, Matt, our resident ethicist, was always flat out. He juggled volunteering in the school veggie garden, playing sports, sibling duties, music practice, and chores around the house.

But do humans try to do too much and is okay to just simply do nothing when there are so many important things the world needs?   Summer Hill Public School: Dimitri, Mia, Teddy, Milla, Cleo, Marcus

It's fun to hang out with our friends, but sometimes we need a bit of alone time. Maybe you want to listen to your favourite music and sing along loudly. Or curl up in a special place and read a book. So should you always say yes if someone asks if they can come over to your house?  Thanks to Melissa for this curly question! 

We all love getting presents, but what about when you get a gift you don't like and will never use? So what should you do with unwanted gifts? Is it ok to give them away or do you have to keep them forever? Thanks to Oscar for this curious question!
