Growing up I was well aware of 'stranger danger'. You know: don't take candy from strangers, don't get into a car with strangers, don't talk to strangers.
Now a'days stranger danger takes on a whole new meaning with the word wide web. When I get email from someone I don't recognize it almost always gets deleted immediately. When someone asks to be my friend, or sends me a message on Facebook, I always check their profile and our mutual friends first. If there are no mutual friends I'm especially careful about accepting friend requests, and 99% of the time I don't.
But.
On Wednesday we drove an hour to the Kilimanjaro International Airport to hug a lady & her husband passing through from California. I'd never met her before in my life, but her hug was the warmest, most sincere hug I'd never expected to experience.
