Reaching up to the wall, I rap my knuckle four times. Like clockwork, she knocks three. Four knocks for four letters in love. Three knocks for three letters in you. It’s something we’ve done ever since we shared a wall. It’s a gentle reminder that even though I’m angry, irritated, or even sad, at least I have Lia, my best friend, the one person who can so easily put a smile on my face. I don’t know what I’d do without her.
