history: I just went to get an oil change the other day, and after I dropped it off, the mechanic said I didn't need one for another 1,000 miles. Felt like such a fool.

Dont be hard on yourself. 
current: Agreed, and it had been 5 months so I figured I was due. The mechanic was really condescending which was what made it embarrassing!
next: Thats so silly its none of his worry. He needs to hush up. lol
