How to learn to refuse?

1) During the conversation, try not to interrupt the speaker, show respect for his situation and request 2) When refusing a request, do not delve into the detailed reasons for the refusal. Suffice it to say that at the moment you do not have such an opportunity (in a suitable interpretation) 3) If rejection is difficult for you, especially when you are taken by surprise, ask for an opportunity to think. During this time, formulate your refusal.
