My husband is a really good mechanic. He loves to use his tool to repair machinery.
What do mechanics do besides repair?
He loves to work on cars? I know this is off subject, but do you know the characters on 90210, the teen drama?
No I don't 
It is a show about a family who moved in order to take care of Harry's mother Tabitha. It was a really good show.
Oh ok, do mechanics do preventative stuff or just repairs?
They can do both. In 90210 the first actor was Dustin Milligan in April of 2008 and then came AnnaLynne McCord.
