I should be
What you're thinking when your homework is sitting there like it's judging you. You're distracted by something dumb, probably your phone.
I should be doing homework. Instead I'm looking at my phone like it's the most important thing in the world.
I should be listening to my teacher. Instead I'm texting my best friend about the dumbest thing ever.
I should be finishing my math. Instead I'm looking at memes like it's a full-time job.
