Do you want to please someone you just met?
It's much easier than it seems at first glance!
It is enough to use a few simple psychological techniques.
Smile
Let's start with the simplest "trick". Smile!
Smiling is a sure way to gain trust and good attitude from others.
But don't overdo it. A smile should only evoke positive emotions in your interlocutor. Don't make a silly smile, don't turn it into a "grin".
And don't let your interlocutor feel like you're making fun of him.
Self-irony
But you can laugh at yourself. And even need to.
Don't be shy about showing your weaknesses and admitting your mistakes. Show a light attitude towards your own shortcomings.
This behavior almost always wins people over.
Call your interlocutor by name
And don't forget to address your interlocutor correctly.
Use the pronouns "you" and "you're" less often, and pronounce the names of the people you are talking to more often.
Almost everyone likes to hear their own name. Why not take advantage of it?
