Tak had came to invade Earth, failed, tried again and again, and failed again and again. She decided to give up and try to live on Earth-she couldn't go home till she invaded and that wasn't going to happen. All because of one boy...

Zim's POV
The idiotic teachers at our highskool decided it would be a good idea to place the Dib and I's lockers right next to each other, so here we were, standing there and arguing with each other. This time it wasn't about anything too important, just about if Gretchen still had a crush on him. I was arguing that she did and he kept protesting against it. We must have been so caught up in our bickering that we didn't notice Tak walk up to us until she cleared her throat.
"Hey Tak." Dib said, forcing a smile. "What's up?" Tak's face was flushing pink and red and she looked at him nervously.
"Hi... Dib... Um..." She sputtered, jeez, is it really THAT hard to talk like humans? You'd think her PAK would be able to function properly and translate human language correctly by now. "I have something really important to ask of you..." She glanced at me then continued. "Will you..." No. No she better not- "Will you go out with me?" I looked at Dib and expected to see him looking as disgusted as I was, but he wasn't. His face was slightly pink and he had a dorky grin plastered on his face.
"Of course I will!" He stated happily. Gretchen had walked into the hallway with a letter in her hands right when he said that. She looked at me and I shook my head at her, making her drop the obvious love letter for Dib. She started bawling and ran off down the opposite end of the hallway. "I guess you were right Zim." Dib said as he looked on at her.
"Poor girl." Tak said, shaking her head. "But anyways," she continued, "the skating rink is open from 7:00 PM to 10:00 PM this Friday, wanna go?" I didn't need to stay around to here the rest.
"Congratulations.." I mumbled as I slammed my locker closed and stormed away. I decided that I didn't need to go to skool the rest of the day, eighth hour was the only one left and it wasn't important enough to stay around. I'm already almost failing all my classes.
When I got home Gir greeted me happily, as always. This time I didn't yell at him for jumping on me though, I just held him close as liquids started to burn my eyes and face. I laid on the couch and looked up at the smoke and steam that was coming off my face. This had never happened before, I'd seen it happen to Dib though.
One time it was when we were kids. Gaz had just told about how the world would be a better place if he wasn't around. It happened recently too, he had talked to his creator and he'd said that he was nothing but a clone of 'The Great Professor Membrane.'
Apparently, this happens when you're what the humans call "sad." Liquids similar to rain would poor out of your eyes and down your face. But why would this make me sad? I don't care about Dib or Tak! I only care about myself.
Right?
