Scenario:
You invite someone you think of as a "friend" to your party.
You wonder why your "friend" does not respond to the invitation you sent him.
He does not even say yes or no. You ask him to answer, but still no response.
You remind him again that you must at least have a reply, still no response.
On the evening of your party, other friends of yours approach you and
show you live pictures of that "friend" dancing at another party - even financing it.
Worse yet: Your "friend" is listed as sponsor of that other party!
But you did not get any response at all.
Is this a "friend?"
