I couldn't get into my car in the parking lot the other day and something was wrong with the lock, so I called a locksmith out to open the door and then realized, it wasn't my car. I wanted to crawl into a hole.
Hahaha. I'm so sorry, but that made me laugh. I really don't mean to make you feel like I'm thinking you're dumb, because I don't. Everyone makes that mistake. I have an old Honda Civic, and I run into that problem, too. You probably gave the locksmith a good story to tell, and made his day. Hopefully you can smile at it tomorrow.
Ha ha.  I'm already laughing about it so no worries.  I felt like an idiot but also grabbed a picture of that car and my car and it even had the same beach sticker on the back of it. It was crazy!  Yeah, the locksmith was so nice that he didn't even charge me.  I was surprise but I guess he felt sorry for me.  he he.  
Oh man, he didn't charge you? You both kind of won then! A good story for you both at no cost. Well, except for time. It was a good learning lesson. And yeah.. the bumper sticker.. that's crazy. I'm glad you're able to not take yourself so seriously. That makes for a great personality.
