When someone is setting a clear verbal/non-verbal boundary and saying,
“I’m not interested in speaking to you.”
You are supposed to stay away.
..
Unless you are a family member, best friend, boyfriend/husband,
you have no right whatsoever to approach them after that boundary.
Because you don’t have that kinda rapport or connection with them.
Even if you are a family member, best friend, boyfriend/husband,
after a certain point you cannot cross that boundary.
