14. Pregnancy announcement
This one is just perfect for couples! Just make sure you don’t hesitate while you’re saying the happy news to your boss. The story goes like this: your girlfriend has just found out she’s pregnant this morning, and she needs some support. Isn’t that lovely!
The good sides of this lie are that you can plan it ahead if you have to take the day off for an interview or something. The bad side would be you would have to face a couple of congratulations the next day, so how about saying it was a false alarm.
