Is there an adjective to describe someone as if he/she acts like they're really close to someone?
I'll try my best to give a context. In this case, a narrative. For a convenient reason, I'll use pronoun he.
Suppose there's a stranger you've seen for the first time. Suddenly, he calls you by your name even though you've never met him before. Then, he starts a conversation with you. He tells about himself and introduces his family and asking you a few questions. It annoys you since you don't know who he is because you've just met him. You also feel a bit uncomfortable because he knows your name and he's not supposed to know. As if you're not ready to build a relation with him. In fact, he realizes that he has just met you for the first time as well.
Perhaps, it's roughly similar to to be friendly. But in this case, saying being friendly has a positive connotation and the word, that I'm looking for, has a rather negative connotation. What is it?
