> and I know I'm going to be staying late until it's done.

I cant tell you how many times I spent long days, 16 hours at a time, sometimes over the weekend etc. Only to have the manager stroll in monday talking about how great their weekend was, and barely acknowledge the item was completed. And then I find out the customer that "needed this so bad" didn't touch it for the next month. Or were never told it was deployed etc.

So many deadlines are fake that it's hard to trust any deadline.
