My kids regularly come home from preschool raving about how much fun they had. But then when it's time to drop them off the next morning, they forget all about that and cry at having to leave me. One thing that helps: a selfie video.

As a new employee, there are a few pieces of advice you'll hear over and over again: Come in with a good attitude, offer to do extra work as often as possible, and never, ever, cry at work. But the fact is, you're human - you're going to cry. Rather than avoid it at all costs and reprimand yourself for not keeping your emotions in check, it's better to prepare for the time it happens.

If you have kids, you have crying. They cry because their brother got to the door first, because they tried to ride two scooters at once and fell, because they are dressed as Batman but do not want to be addressed as Batman by other shoppers in the supermarket.

There are so many reasons to cry! And when you've had it up to here with the squabbling and fighting and crying -- especially about some nonsense you don't have time for, like who pressed the elevator button -- it's really easy to say (or scream) "stop crying!"
