Hippopotomonstrosesquippedaliophobia: The fear of long words.
If Modi were just a little bit older, he would declare that reading was a pain in the ass.
However, since he was but a tot, he only managed to voice his displeasure by biting Loki rather fiercely on the arm as Loki reached over to turn the page of his Dr. Seuss book.
"My God," Loki curses to himself in Jötunese, "what circle of hell did you demonspawn crawl out of?"
Modi looks at him innocently and smiles gummily at him, displaying little fangs in the making.
"Dat word too long," Modi protests as Loki points to the word "mouse." "Longer dan my name."
Loki sighs, rubbing his forehead irritably. "Yes, it is longer than your name. Now do you know what it says?"
"Moose."
Loki opens his mouth to protest, before deciding that "moose" is relatively close to "mouse," and dropping the subject.
"Dis word vewy vewy long," Modi squeals, jabbing at the word "refrigerator." "I do not wike it."
"I concur," Thor roars from the other end of the room, and Loki almost falls over with the sheer volume he produces.
"Yes, well, you should at least try," Loki says, trying not to lose his temper and simultaneously trying not to laugh helplessly.
Modi squints at the word, sounding out the syllables. "We...fwi...ge...way...tor!" he pronounces after several long minutes.
Loki smiles tiredly at his son, and Modi claps in delight, conjuring a refrigerator out of nowhere that lands directly on Thor's toe.
Thor asks Loki to please proofread the next few books so as to avoid long words. His son, and his foot, would gladly thank him.
Loki can only oblige.
