Stacy was much more than you. She's a Harvard undergrad and you're a community college dropout. And now that you had the shrinking virus...She was much stronger and bigger than you. Rebelling would have been completely useless, so all you could do was stay silent and lay there, stuck to her sweaty sole; hopeless while she laid on the couch with her feet up reading a book. It was hard to think that this gigantic monster was your big sister (Technically half-sister).
You tried voicing your complaints. You two didn't alway get along, but neither of you hated each other. You thought there was respect between you two. You kept telling yourself: "I don't deserve this!"
Stacy heard your tiny voice and got annoyed. "Keep licking, you little bug! Stop whining! Unless you want to end up squished under my foot!"
