A Takeaway is to make somebody desire something more by making them think they're lost/ are losing it. A classic examply is taking a babys food that wont eat..now all of the sudden they're hungry. A great way to administer this is after already declaring a 'time constraint' and then at pauses in the conversation, or between multiple questions in a canned routine to slightly turn either shoudlers or full body, or take one step away, the swing back and pick up. in that moment you can set the hook after they thought the fun/ interesting interaction is over.
This technique is used all throughout relationships/ interactions to build need and make the target work for attention. Used to combat Last Minute Resistance to kissing or sex.
