Remember the sisterly love?

Getting along better, doting on their brother, what sibling rivalry?   I know that there will be clashes from time to time, and figure that is probably healthier than annoyances bottling up forever.  In fact, I was rocking Nicholas to sleep tonight (very quick tonight, given his lack of a nap this afternoon) and I thought I heard a bit of an argument. No big deal, it happens, right?

Nothing terribly loud, no screaming, but we have thin walls (card stock is thicker) and the voices were definitely raised.  Then everything was quiet, doors were closed (not slammed) and I decided all was well…until I carefully shut the door behind me, walked over to Kelsey's room to give her a kiss good-night, and found the above sign on the door.

 She has had signs before such as, PRAVATE – Keep out!, but nothing this detailed.  Though for all I know, the last sign was directed to Nicholas, as he now has a penchant for touching and occasionally filching her stuff.  This new directive (or list of directives) is so specific, that I know the recipient of her ire is her next-door neighbor.

So, here's my question:  this is normal, right? They will look back one day, laugh about their petty differences and be the best of friends…correct? 

I know I probably shouldn't think twice about it, especially since Cait's only reaction to the note was a giggle.  Each time I see it, though, I think of the siblings I see, whether at school or church, who never seem to argue and simply adore each other.  On the other hand, Cait's not upset, Kelsey is happy to have the sign on her door, the baby is snoozing soundly, and if all goes according to plan, Peter comes home tomorrow. I think I will enjoy her creative spelling and leave it at that.
