Moving Help

Why do we help our friends move away from us? If you think about it, it's a little bit silly. Do we want them to go? No. Does our helping make them feel like we can't wait to get rid of them? a bit maybe?
I'm sure any help is appreciated to ease the basic stress of moving, but...
Shane's best little bud and his family (good good friends) are moving away. We've spent a couple weeks helping pack, cleaning and watching boys. They've been staying with us while they wait for a space to open up on the little plane that will take them to thier new home on the other side of the island (Hidden Falls- a Fisheries community). For the little ones, it's great friend-overload, so maybe we'll have a little break before they start asking for each other.
Personally, it's weird enough not having her at work these days. I'm still in denial that she's leaving to a limited communication area. sigh.
