[HIGHLIGHTS] What does the protocol say about being grateful? You always have to say thank you, but, be careful, without going overboard or screwing up.

From Seneca to our grandmothers, great minds never tire of emphasizing the importance of being grateful. The word 'thank you' should be loaded with truth, with emotion but without going overboard if you don't want to end like a Goya.

Protocol recommends not talking about money on social occasions, but we are in trust, says the Protocol expert. If you want to accompany the word thank you with a fact that supports it, you can send a detail to the person you are thanking.
