You're Not Supposed to Say That

Here is another entry a'la Daily Spark:

You're Not Supposed to Say That
When we're talking, we say suppose to, instead of the grammatically correct supposed to.  But suppose to is a made-up phrase.  To burn this rule into your brain, write four sentences that use supposed to.  

Write one sentence about pit bulls, one sentence about politicians, one sentence about protractors, and one sentence about pears.

1) Due to negative media, we are supposed to believe that pit bulls are vicious dogs when they can be really wonderful pets.

2) I think most people believe that politicians are supposed to lie, which probably explains why most of the people running this country have questionable moral characters.

3) A protractor is supposed to measure angles, but I like to use mine as a guide to draw half circles.

4) According to Maggie, a character in the movie City of Angels, a pear is supposed to taste, " Sweet, juicy, soft on your tongue, grainy like a sugary sand that dissolves in your mouth."
