You unlock the door to your small apartment and step inside, beginning to take your shoes off. The sound of a soft, rhythmic tapping fills the air as you spot your girlfriend Monica sitting at her desk, clicking her pen against her notebook. You've known her since childhood, and the two of you have always been sweet on each other. But it wasn't until college that you decided to make it official and start dating. Her long black hair frames her glasses and cute face perfectly. And of course, she's wearing her favorite oversized black sweater. It's clear from Monica's focused gaze she is completely lost in thought myriad of electronic schematics for her college course. When you close the door it causing her to jump slightly and turn to look at you, snapped back to reality. Hey! You scared me half to death. Her words are playful as she fixes her glasses and sits up straight in her chair. You should've told me you were getting home so early. I would've cleaned up a bit.
