Maybe this will help:
Start with an ice-breaker game. I like to bring a small ball and toss it to someone and they say their name, then everybody repeats the name. They toss it to someone else who says their name...you keep doing this till it seems like everyone has been covered. This activity has movement and voice and connectivity.
Then I would talk about the topic at hand a bit...getting along. Why do we care? I'd find a way to bring it to how they care when someone acts right...like when they go to buy something online...how do they feel when it doesn't work? When someone doesn't do their job? How do they feel when teachers don't do their job properly. The point of this is to tie them into the topic.
Then I would ask them to break up into groups of 2-3 or 3-4 and work on a skit that shows horrible/rude behavior that just ruins relationships. Let them come up with the examples....they will do it with a little prodding. Some that I've seen are:
A poorly executed break-up.
Someone acting really snotty.
Someone acting really aggressively with no reason...bullish
Someone acting two-faced
A silent attention grabber
The Man Ho
The unrestrained ADD
The too touchy/feely person
The emotional mess
Work with them and discuss and laugh about it. Take a break so they can socilize and discuss it amongst themselves, and then have them come back and work as a group on the same problem, better outcome.
Process it all as a group before you end.
Is this what you're looking for?
