Profound conversation with my 4-year old son

The following is a conversation I had last night as I was tucking my 4-year old son, Alex, into bed. Autumn is his 7-year old sister.

Alex: I have a cramp, and I think my toe bone is almost broken.

Me: Oh no, we'll have to check it tomorrow and see if it's okay.

Alex: How can we even do that?

Me: We'll just see if it still hurts in the morning.

Alex: I think I'll know if it's broken even since I'm four years old. I don't want to have a broken bone, and I don't want to die either.

Me: You don't want to die?

Alex: Yeah, but I think everyone has to die.

Me: Well, that's true, but I hope you don't die for a long, long time. I think you'll live a long life and be very happy.

Alex: Autumn said everyone has to die sometime or somehow.

Me: But you know what? No matter what happens, I will always love you, forever. And Mommy will too.

Alex: I will always love you, too. And Mommy, and Autumn. And I love Netflix.

Me: They have good stuff to watch, don't they?

Alex: Yeah, like Sponge Bob.

Me: Good night, I love you.
