Cell phone and ping questions aside, I can't understand MR's actions or inactions when he gets home at 11:30am.
--He knows Dylan was desperate to see his friends.
--It's absurd to think Dylan would walk the 20 or so miles to his friends' house (how long would that even take? How many hours?)
--If he thinks Dylan would try making his way to his friends' on his own - how is he going to get there? No bike. No bus or public transportation. Doesn't seem like there are any close neighbors or friends MR could assume Dylan safely got a ride from.
.....
-- A reasonable mind might think a 13-year old would call his friend's parents for a ride.... DH suggested this on the NG show, saying Dylan would call someone's mom for a ride or at least try. But that would mean either the cell phone and/or landline would have to be used or an attempt at dialing out would be necessary in this "story".
-- So MR arrives home and apparently somehow thinks Dylan made his way to his friends house safely, enough so that he doesn't really get alarmed until late afternoon.
-- Only later does he even consider hitch-hiking "in hindsight" after learning from Dylan's friends that he's been known to hitch rides, though all we've heard is the one group incident of hitching.
I can understand being surprised to learn your child may have hitched rides before, but the only safe situation was if Dylan ended up at his friends' and got a ride from someone reliable and trustworthy (and likely known to MR and Dylan). Yet it took several hours of not trying or not being able to reach Dylan to confirm that he made it safely, while all the meantime something bad could've happened like being hit by a car or falling into a lake or down onto rocky ground.
I guess he's just a calm, cool, collected, go-with-the-flow, assume everything's going well, things are just fine, Dylan made it and there are no worries kinda-guy.
Just my thoughts, but I don't get it.
