Trogmire Troll was dealing with a crisis. The new girl in class really liked him a lot. Trogmire was not happy about it.

Trogmire’s good friend, Tremor Troll, tried to comfort him.“What’s the big deal? I think Treasure Troll is kind of cute. And she seems to be nice enough.”

Trogmire swallowed his last bite of salad and glared at Tremor.“Then why don’t you ask her to be your girlfriend? There she is, sitting all by herself at the other end of the cafeteria. March over there and ask her to be your sweetie-poo!”

“She’s crazy about you, not me,”Tremor replied.

“Well, I don’t want any girlfriend, especially not a weird(古怪的),annoying one like her!”Trogmire growled(to make a sound to show anger).

Tremor wouldn’t give up.“The only thing annoying about her is that she keeps writing you those notes and she stares.”

“Annoying love notes!”Trogmire interrupted. He took another sip of milk.“Did you notice those strange brown eyes? Why aren’t they normal red or pink?”

Tremor took another look at Treasure.“I think her face is a lovely shade of green. And her dark green curly hair is quite pretty. Besides, she’s very sweet and that’s what really matters.”

Trogmire stuck out his tongue.“I think I’m going to be sick! I’d better save my apple pies for later.”He crammed a small bag of Maggot Munchies into his even smaller shirt pocket. “The fact is, I have a problem. That girl is getting on my nerves!”

Tremor followed Trogmire’s example and decided to save his apple pies for later. However, he carefully placed the bag into his lunch box.“Do you have any ideas about how to solve your problem?”Tremor asked.

“I’m going to be mean and rude to her,”Trogmire announced.“I’ll call her names and make ugly faces at her.”

“That’s how you treat everyone,”Tremor reminded his friend.

Trogmire nodded.“It’s time that Treasure got to know the real Trogmire Troll!”
