Who has met Loki?
Tricksters abound in many cultures. http://en.wikipedia.org/wiki/Trickster
Be they in the form of Puck, Loki, Brer Rabbit, the "Gentle Folk" of Ireland, or whatever, the Hobgoblin is always ready with "advice". Such advice is always seductivly expedient, and often very risky to follow. And we know this, but still listen to those mischievious voices in the ear.
Here is a good Puck (Robin Goodfellow) resource: http://www.boldoutlaw.com/puckrobin/puck.html
On Loki: http://www.octavia.net/vikings/loki.htm
and I quote:
"His activities ran from the merely mischievous to the blatantly malicious. Supremely clever, Loki ensnared everyone in complicated problems, to which he always supplied a remedy - through his solution often engendered even greater troubles."
Have you ever heard the Hobgoblin's advice?
Here are some common ones:
"You're tired now, leave it till the morning when you are fresh again". (Homework, ironed shirt for work etc)
"One more pint, just one, you'll feel fine in the morning".
"Don't stop for directions, you'll find out where you are as soon as you crest the hill".
"Buy it, yes buy it now. You can sort out the credit card later".
"You don't need oven gloves. It won't be that hot".
"Go a bit faster now, there are never speed-traps on this road".
"We won't be out for long, and the weather is fine. Don't bother with a jacket".
