I love you.
The three most simple words to explain the biggest human experience.
Because it will never fit inside a sentence well.

How can you fit lingering stares, reminders of "text me when you get home so I know you're safe," midnight tums runs, laughed-filled kisses, sticky fingers, "I made your favorite," gentle caresses, wrinkled hands held across a park, and memories into one sentence?

You can't.

We have to oversimplify the most complex thing because while it is real we cannot describe a law of force that isn't confined by limits.
