I care about them, etc.
Every teacher is different, every kid is different.
I go by feeling and intuition. My philosophy is that each situation demands a different approach to account for the differences that exist. Being late to my class means you're gonna miss something important, wether it is practicing your writing skills, discussing literature, or not having enough time to complete an assignment. If a kid wants attention, I give it - but not at the expense of the resat of my students, which is why I'm in early and leave late, coach sports for the school, etc.
