Unfortunately, layoffs are going around everywhere. I was laid off the week before Thanksgiving. What a great gift!
My boss didn't even know that I was going to be let go, his boss (who's in another state) gave me the news. The worst part (other than being jobless) is that my boss and I had a great working relationship and we got along really well.
At least you dodged the bullet. I wouldn't let the extra drinks get you down, this was a "special" occassion and not something you do everyday (calorie wise). Just start fresh again tommorrow!
