Overview
There's one primary thing to keep in mind today -- have fun! But don't think that having fun can't require just as much work as anything else. You will need to be the person to initiate the action. Some folks will be too focused on their tasks to want to come out and play with you, so you might have to do a tiny bit of good-natured arm pulling. If you show them a taste of what they're missing out on, you will be able to get them to join in!
