Ok, he was up until 4 am, that means he went to bed right? Do you know if he woke up at 6 am and only got two hours of sleep or did he wake up at noon after 8 hours of sleep?
If he woke up at noon, he had 8 hours of sleep, his flight arrived at around 6 pm, so perhaps let's say it took off at 4:30, it's not like he's traveling through a MAJOR airport, you can spit from one side to the other of both Colo Springs airport and Durange, so I don't see him having to get there two hours early to account for security & check in. Give the benefit of the doubt, he got to the airport at around 230.
So you have a child that had about 8 hrs sleep, packed his stuff, left for the airport and 6 - 8 hours after being awake he was exhausted.
REALLY? Again, if he only had an hour or two, even 4 hours of sleep I would maybe buy exhausted.
Do you remember when you were young, party all night, little sleep, up and at 'em in the morning. Younger people have more bounce than us old folks. :floorlaugh:
