You can get things done very easily and smoothly by just understanding human nature , by nature we all love to hear good and positive things about ourselves - so before you get to point where you can hurt someone just figure out what are best qualities in the person and say something which will make them feel good and confident but keep in mind that not doing this sincerely will make them feel like you are faking and buttering which can make things go wrong so say nice things with emotions and sincerely - then say your point, and see the magic ❤️
