I think were I in this guy's situation,I'd call Mom all right.All she'd be hearing was me wailing "Mooooooommmmmmmmmmyyyyyyyyyyyyyy!"
I'm ascairt of heights(so I became a volunteer firefighter.go figure)so if I had to be rescued like this,I'd at the very least need a change of clothes.Going right back to the "office" would be a decison made after serious thought.
