my boss is having a graduation party for his kid. He did not invite me. But I think social graces say that if you do not plan to invite me to your party you shouldn't talk to me about it. I don't want to know what you're going to eat and drink, since I will not be having any. I also find it funny that he admitted to me that there will be 100 people there. One HUNDRED. And still I am not invited. And one might say "well, if he invited you then he would have to invite everyone from work" and blah blah blah. There are two problems with this statement: 1) he did invite people from work. 2) I am his only employee. So, pretty much he could invite me and no one else. The good news is that your boss' kid's graduation party is not exactly the event of the season, and truthfully I would probably rather eat hot dogs with my kids, but it's the principle, people. Social conscience. Try to get one.
Perhaps even worse than this is that we are facing not getting raises for the billionth year in a row because of state budget issues, but my boss got a big raise and he now makes more than four times what I do. And I have to punch those numbers into budget spreadsheets, and let me tell you it makes me cranky every time.
