Number 4 - The Forgotten Middle Child

It's the number that nobody ever talks about, but everyone secretly loves. Like the quiet sibling that nobody asks to the party, but always shows up anyway. What's your favorite thing about number 4? Is it the fact that it's the only number that's a palindrome? The only number that's also a letter? Or is it the fact that it's the number that's always in the middle of everything?

Maybe it's because it's like the number 4 of the number 1's worst fears: being stuck in a never-ending sea of 5's and 3's, while 2's and 6's just float away with the wind.
