Some of your teaching practices (e.g., asking students to talk to a neighbor) might make them uncomfortable. Explain your pedagogical moves so that students understand your intentions and teaching strategies. For example, if you do not allow laptops in class, share the research finding that when students use a computer during class they learn and retain less, as do the students around them.
Example: "I'm providing this example to help motivate today's content."
