You're in your 20s but have a 70-year-old brain, which means you're forgetful

What you remember is that she is your girlfriend. You love her and she loves you too

Now you two are standing in the apartment, she looks at you with disappointment and a little anger

"Hmmp" she whines, squinting her eyes at you

You realize that today is the anniversary of the day you two fell in love
