Practice making small talk with someone:

• you don't know well

• with whom you find yourself sharing space for a period of time

  • such as online at a store, in an elevator, or while waiting for an event

• you already know but haven't spent a lot of time with them in conversation

• in your extended family, maybe at a family gathering or on the phone
