Working With Immaturity

So help me, I for the life of cannot understand the "boys" I work with. I use the term "boys" because these are grown, adult men who act like boys. They maturity level leaves a lot to be desired. It's as if they never grew up. They play games, act as if nothing really matters, will try their best to just be aggravating all the while aggravating everyone in their general vicinity, and then they think it's so funny. One instance is just dropping something in the floor to make noise. They do this and actually think it's funny. Huh? I don't get it. What's even sadder is that all these guys are married with kids of their own. Rather than trying to set some kind of good example for their kids, they let the kids set the example for them. The kids actually show more maturity and responsibility. This is one reason I look forward each and every day until the time I can retire. It's absurd to the inth degree.
