I love my job. I love the kids. I love my co-workers.
Two years ago at our work Christmas party, one of my co-workers told me a story about something I did earlier that day, that I was completely unaware of and she found quite funny. It was early December and we had a particularly unruly and impulsive group of Team One(12 years old and under) boys. They needed all the support, encouragement, praise and reinforcement of ANY positive behavior possible.
As the boys were walking from the front of the unit to the back after a group, I simply said(and I sincerely meant it), "You guys are doing a really good job walking." As it was highly unusual to see this group of kids actually walk from point a to point b with out spinning, running, skipping, hopping or dropping to the floor and rolling around. My co-worker said at that moment in her head, she thought to herself "Where do we work that we say things like "good job walking" and it is the only compliment you can come up with?" Needless to say, it is now the running joke between her and I to compliment each other on doing a good job walking and have a hearty chuckle.
So, if you are every running short on nice things to say to a person, I would recommend going with "good job walking" and think of this story and maybe, just maybe have a little chuckle of your own.
