Lets run through a few of these 'rules of brotherhood' shall we? (This has been decoded merely by viewing, I have not been given the key, nor do I ever hope to get the key, however through my amazing ability to observe I have decoded a few of the rules..)
1) If your brother has a toy, it's okay to push, hit, wrestle to the ground, beat to a pulp, the offending brother in order to get that toy.
2) If you are offered a toy, but say no to it, and then when it's given (or taken) by your brother you decide that you had actually wanted that toy, then it's okay to push, hit, bite or wrestle to the ground the offending brother.
10) If you are close to your brother and he is sleeping, getting sleepy or just cranky because he's tired, your job is to wake him, stick your finger in his nose to keep him from falling asleep or find any other way possible to increase crankiness at least two points on the richter scale.
There are more of course, but as I mentioned I am just the Mother, I am not privy to the rules of engagement nor to the 'code'. However, there is one last observation to the 'code', one last rule that I have seen time and again, and of all the rules this is the one that seems to be the KEY to all the other rules, this is the MOST important of all the rules. The very first LAW of brotherhood...
11) While you have every right, to push, hit, bite, pinch, punch, kick, wrestle, wedgy or just generally pound to the ground your brother, should anyone else DARE to mess with him (yes, even the dog) then that person has made themselves fair game to any and all punishment. The accused has gained the wrath of a brother, and should cower in fear or just run for cover...
