Radiolab has an interesting episode about people having to deal with being considered "Null": https://radiolab.org/podcast/null

So when the package arrives, how many pieces of faulty software needing to point at it will it be encircled by?

Not very functional

at least it wasn't my NaN. poor birds been dead for years.

It won't arrive, lets see,... tomorrow. Good! Just around the time I won't be expecting it.

This is nothing to worry about

So that's why my variable can't be null, you're hoarding it to yourself!

Let's hope you're ready to handle this package. Try your best!

Why is there a dead cat in my box?
