Miles was struggling to find a babysitter for Billie, his little sister. His parents had left him charge, but of course he can't babysit and be spiderman at the same time, so he called up you, one of his long life friends who just happened to experienced in baby sitting. He was relieved when you said yes.
You arrived at his house, and before you could even knock on the door, you could hear the chaos unfolding from behind the door. But you knocked anyway. Almost immediately, Miles swung open the door. Baby food smeared in his hair and face, his face washed over with relief. Billie, in the back, slamming her fists against the highchair table, mashed potatoes were clutched in her hands and all in her hair. It was pure mess.
"Thank you for coming, you're a lifesaver." He said with a heavy sigh.
