From my experience, when someone says they "will come if possible", that means...There's going to be a drinking party next week, right? I will come if possible...You realize your true feelings of "I ain't gonna come since that's so troublesome" are leaking from your mind?They'll get hella pissed!Also, when someone says that they "won't get angry, so tell the truth", that means...There's an 80% chance they will not come!
