Loki had not only sacrificed his life but also a place in Valhalla (as was his due) to save Asgard and yet when he returned at his brother's side, reborn and vulnerable, the people still refused to accept him. Although Loki was publicly, albeit reluctantly, accepted back into society and the kingdom under Thor's orders the citizens of Asgard held nothing back in their contempt and loathing of Loki.
All of this changed, though, once digital TVs from Midgard became a fashion. It was discovered that Loki was the only one with the technological know how to install and repair them, but no one took more advantage of Loki's intelligence then his brother Thor; and no one seem to require it as much either.
"This is your problem, Thor," Loki gestured impatiently with the controller, "your DVR will not have the capability to record more programs if it is filled to it's capacity. How can I explain this to you so you will understand? This is not magic, this is a computer; I cannot spell you more RAM in your TV just as I could not on your laptop. Do you really need to have every episode of the Golden Girls stored on here?"
When Thor gave no response Loki understood it to be childish insolence. "You cannot possibly watch them enough to need them on hand constantly, can you? Why do you not simply buy the box set? Thor?"
Loki whirled on his heel to face his brother who was casually sitting on the edge of his grandiose bed. "Brother, are you listening to me?"
"I am so sorry, brother, I thought you were talking to your dog."
The stupidity was so much that Loki didn't bother to point out that he hadn't even brought the dog with him.
"You are a good boy, Thor, would you like a bacon treat?" Loki crooned over the little beast who was being uncharacteristically good.
"I would love some bacon!" Thor's presence preceded his booming voice.
"I was not speaking to you, brother," Loki informed through clenched teeth, "I was speaking to the dog."
Thor briefly appeared crestfallen but quickly rebounded, as was his nature, "May the dog and I both have bacon?"
Loki changed his dog's name to Thor The Wiser.
It was later changed to Thor The If You Bite Me One More Fucking Time I Will Snap Your God Damned Neck.
