A word of advice to all of you:
Don't say you're going to do things...and then not do them.
Let's suppose, just for an example, that someone decided to have a birthday gathering. And they asked people to let them know if they would be coming. It would probably be a good idea, if you think there's a chance that you might flake out, that you shouldn't tell them that you're "definitely coming".
Well, perhaps the person wasn't planning on having a big party.
Perhaps the person announced the party on late notice, and, when several people said that they were unavailable, was thinking of postponing the get-together; but when a few of his friends said that they'd love to come, he decided to go ahead.
Perhaps the person sat by himself in the bar for an hour.
Perhaps only two people showed up at the bar during the three hours he was there.
And perhaps, perhaps, the boy who was throwing this party, normally a pretty stoic guy, was feeling pretty lonely that day, and just wanted to hang out with some close friends. And their absence only made those feelings worse. We might even go as far as to say that the boy's feelings were hurt.
