boys & their bathroom manners (or lack of)

There are times during the day that I just shake my head & I sigh.  I do not understand these sons of mine. Their bathroom manners are weird. Here are a few stories that I hesitate to share because they may or may not be normal stories. I do not know. I did not grow up with brothers.

*Andrew - he was nicely playing in the living room when he gave a loud shout "I've got to go!' Before I could blink he ran past the bathroom & tore outside to my beautiful magnolia tree and proceeded to pee on it. After he was done, he came right back inside & continued to play.
If we are outside & he needs to go to the bathroom it takes him a long time to make a decision about which tree to go to. It takes him so long that I fear he will have an accident. I am sure that he thinks that he is doing that tree a huge favour by peeing on it. But we have come a long way from last year. In the nic of time I stopped Andrew from peeing on a fake tree in the house. At least he now knows the difference between real & fake trees!
A few weeks ago I asked Andrew what his very favourite part of Up North was (campfires, boating, fishing)  he quickly replied, "going to the bathroom."  whaaat?!

*I have had boys go on the toilet at the same time and do their job. They were very proud of themselves for that stunt. That will not happen again.

*And for the climax. Not long ago, the two oldest boys were becoming increasingly excitable. That is my new word for hyper. I told them to take it outside & if anyone gets hurt, not to come to me. You know how it goes.
Again, before I could blink, they are peeing. This time though, they are not peeing on a tree but on eachother...I flipped. I ran outside & told them to stop, but I guess that it is hard to stop mid stream. Apparently this is called "swords." They didn't know what to do & neither did I. Am I missing something because I just don't get it. I gave them two of the smallest scrub brushes that I could find & a pail of soapy water. I told them to wash themselves & to start scrubbing the patio. Surprisingly, they ended up having a water fight. (believe me, I did see that one coming.)  Did I do the right thing?  Did I over react?  Is this something that all young boys go through? I do not know. But I do know that scrubbing the patio/water fight kept them busy & out of more trouble until supper time & that is what counts.
