Love.

I don't know much.

I don't know what's going to happen today or tomorrow or the day after that. 

I don't know if we'll ever have kids or if we'll have a ton of them or if we'll be somewhere in between.

I don't know where we'll live in 10 years or what we'll be doing.

But, I do know that when I'm old and gray I want to be like this.
