It's very true that some people get high hope whenever someone promised them something but on a second hand it was not supposed to be so, because we are all humans and we are bond to fail at some point.

That's why personal I don't trust people words, it's only their action I can act on.

I'm sorry about your fail job promise, I equally had such a failed scenario, a big family friend, a well to do personality in good standing in my state, promised me job on two occasions but failed me at the end.
