My youngest brother was like this. He's 7 years younger than me. More often than not, I was in charge of him! But even when my parents were watching him, it's NO ONE'S fault, he's just 'that kid'...
Places he's disappeared and where we found him:
*West Point, NY, other brothers hockey game: last seen: coloring in brown crayon on the plexiglass. Found: In the PROFESSIONAL hockey players locker room (they were about to make him the mascot).
*Ocean City MD, Assateague Island National Campground, last seen: Sleeping in the pop up trailer. Found: 9 blocks down the main road, riding his tricycle down the yellow line with his little orange flag waving; told the coast guard that found him 'I'm going to see Aunt Dee' (who lives in CHARLOTTEVILLE, VA!!!)
*Ringwood New Jersey, Ringwood Elementary School soccer field: last seen IN HIS STROLLER next to mom. Found: in the cafeteria, on top of a table (we still don't know how he got in; the janitor, who's kid played on my team, had to let my parents in).
*Richmond, VA (he's an adult now): last seen: backing out of my parents driveway. Found: UPSTATE NEW YORK. He got SO lost, kept driving, ended up in upstate NY, got MORE lost on the way back, stopped in Philly, eventually made it to Alexandria, VA, where I told him to STAY PUT!! until I got there; had him follow me home.
These are extreme examples, but heart stopping none the less. He's a great kid, he just has a history of LEAVING and GETTING LOST ;) He's fantastic! Out of all the bad things that COULD HAVE HAPPENED, none of them did (thank god!) and he's fine ;)
