Because they are!!!
It sometimes is for the right reason, but I do 100% agree that it does seem selfish, I would HATE to have to do that!
Um...C? That's a weird question...
Man vs. self refers to someone who is having conflict within themselves. They are having trouble solving a problem for example.
Answer:
Very important. Each paragraph should begin with a topic sentence setting out what will be discussed. The body should contain properly structured sentences (no fragments or runons) containing supporting details—examples, explanations, or events. The concluding sentence should indicate in some way that the topic is completed or hint at the topic of the following paragraph. The writing should be concise but meaningful using well chosen words and avoiding repetition (except for rhetorical effect). Avoid bland words and cliches, and look for verbs that convey two ideas (such as paced for walked nervously) and replace it and they with the names of things.
