I now ride horses and run for fun.  I am lazy however because as I mentioned before I don’t have much endurance.  I’m a sprinter through and through!  I like the pain to be over in less than 60 seconds.  I am able to run longer but wasn't usually happy about it.  For as much as I love sports I also love to sit on my couch with potato chips and watch tv too!  Generally I love athletics but I am a lazy relaxer also!

It was about halfway through his last set of conferences that Mr. Man realizes (1) he did not (2) much like his current set of students.  Unlike his students in the past, none of them seemed to care about their (3) grades, (4) none of them was able to tell a dangling modifier from a participle, (4) and, apart from a few, (4) they didn't know (5) how to start a paper.  He would never tell any of them this, of course, (6) they might get offended, and if there was one thing that Mr. Man learned (7) about teaching, its (8) that in order to keep one's job, you couldn't offend your students (9).  As yet another student whined about not understanding Mr. Mans (10) perfectly clearly written assignments, he sighed inwardly (and possibly outwardly as well), (11) and waited for the last (12) one to finish so that he could get to the next one, finish his conferences, and get back to daydreaming about being anything but a teacher.

In the last day of classes (1), everyone was distracted and unable to do their (2) work.  Even the teacher, which normally (3) was attentive and cheery, seems (4) unable to focus.  The final test took (5) way too long for everyone to complete, and many of students (6) had put down his head (7) on the desk.  The sound of the heat blowing through the room was enough to put everyone (8) to sleep, and the teachers' (9) eyes began drooping despite hisself (10).  After what seemed an eternity; (11) the bell had rung (12) and everyone, including the teacher, ran out of the room.

My lunch I had with my friend Gary (1) did not go very well. For one thing (2) he said he would come to pick me up (3) at noon. He normally texts me when he's outside, so I waited until 12:25.  Finally, at 12:30, he sends (4) a text: "Left my phone at home and had to come back to get it since you weren't downstairs waiting."

When he came back to get me, he was mad, at me. (5) "I couldn't find your doorbell," he shouted, "because there was no name tag on it, so I had gone (6) all the way home to get my phone just to text you!" (7)

"Wait a minute," I said, starting to get angry myself, "you're mad at me because you left your phone at home and you couldn't find my doorbell?"

"That's right," he replied __________ (8). "If you had been waiting downstairs, I would have had to not go through all of this." (9)

"But you're the one who left your phone at home," I countered, "and you always text me when you get here. Never have you asked me (10) to wait outside for you."

"Well, you should have," he muttered.

The rest of the day goes (11) downhill from there, all because my former friend Gary is (12) too proud to admit when he makes a mistake.
