Having a younger sister sleeping on your shoulder is a lot like having a pet sleeping in your lap. You concentrate very hard on keeping still, even when it gets uncomfortable. Especially when it gets uncomfortable. You feel their every movement and when they start slipping, you adjust into even more uncomfortable positions to prevent them, or her head, from sliding off. All the while, you’re pouring into them all the love you can possibly muster. You’d let these moments last forever if you could because it’s one of the most precious moments you have with them.
