Write ten sentences containing pronouns.

I think that this can be done quite easily.  If you are
writing a paragraph about the worst time in your life, or a time in which you were the
happiest with others, this could be done quite easily.  At some level, it would be easy
to do because when we write about or tell stories about situations, we use pronouns to
simplify the process.  It ruins the flow of the story to constantly use proper names and
nouns.  At some level, substitutions are needed in order to maintain the focus of the
story.  Try this yourself:  Describe a situation without prounouns.  The situation would
be quite awkward because the situation's development would be stalled by constantly
referring to proper nouns in the situation (I just did this here with "the
situation.")
