I heard someone on TV last night describe their relationship with someone as a roller coaster -- lots of ups and downs. This is a bad metaphor. On a roller coaster, the downs are the parts that are the most fun, which is not true in a relationship. The ups, while not bad on a roller coaster can't compare to the downs. And of course, the ups in a relationship are the best. Because of this shoddy cliché, if you ever say to me that your relationship is like a roller coaster, I will assume the following.

-- You had to wait in line for 30 minutes to get on your relationship.
-- You were wearing a shoulder harness and a lap belt the entire time.
-- When you went upside down, change fell out of your pocket.
-- You put your arms up and screamed during the downs.
-- When it was over, you were either incredibly happy, or you got a little nauseous (which is really the only thing roller coasters and relationships have in common).
