1 . Have you ever wondered if you see the same colours as other people? Most people know what blue is when they see it. They call it "blue” because they were taught the word and connected it with what they saw. But how do you know what you see as blue isn't someone else's red?

The ability to perceive （感知）different colours is up to receptors （接受器）in our eyes. Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then reads these signals to determine which colour light the eyes are receiving.

Some people's receptors are more developed than others. The inability of the receptor to feel the light waves correctly means that some people cannot tell the differences between similar colours. Those with more developed receptors can see more colours. We sometimes hear people having an argument about whether something is dark blue or black. It might be because one person has stronger receptors to feel the light than another.

In the past, most scientists would argue that everyone saw colours in the same way. However, research was conducted on monkeys, in which their receptors were changed. This enabled them to see more colours than usual. Normally monkeys can only see blue and green, but the change allowed them to see red. Their brains automatically got used to new colours. This suggests that our brains may find new colors of the things we see. Colours could be a very personal experience , unique to everyone.

So, the next time you talk about your favourite colour, just remember if yours is blue and your friend says red, you two might actually be thinking about the same colour. What if everyone in the world has the same favourite colour, but just calls it different names?

2 . Dear Jack,

I remember the moment— it truly hit me that your autism (自闭症) lasted forever. I had already mentally planned our trips up north with the boys. I was going to spend endless hours playing baseball with you— like Grandpa did with me.

When we said goodbye to kindergarten I knew it was real. I spent some time being sad. Now you are 8. You still have no words. We have never had one of those father-son moments I pictured when you were a baby. But I'm learning that's OK. I still have unbelievable things to offer as your dad, even if they weren't the things I originally expected.

You have taught me to be patient. You have taught me that it's OK to be different and to be sad when life doesn't go as planned. You have taught me that it is OK to talk about those feelings and fight for what is right. Stand up and say this is wrong, and encourage others to stand up for you and say the same.

My job on this earth is to create a world for you and other kids like you. Be the voice you don't have, and build the kind of community which I want to see you grow up in. I used to shy away from contacting people with disabilities or just not consider them. Before you were born, I was so caught up in my own world that I probably wouldn't have even noticed. Now, I see things differently. I notice. You did that for me. And hope my example will do that for others.

Your mom and I have spent 8 years trying to find your voice. And honestly, we don't know if we ever will. I promise you I will spend my life keeping you safe and making this world better for you.
