You guys were right.
It was a vibrator. As soon as it started vibrating and I realized what it was, I threw it across my car and threw up in my mouth a little. I immediately ran into Target and washed my hands a couple of times. I bought some of those disinfecting wipes and used one to pick it up and throw it into the big dumpster in the parking lot. I texted all of my girl friends and asked, "This might be an odd question, but did any of you lose a vibrator in my car?" No one claimed it.
Some of my friends think someone dropped it in my car, because I leave my windows cracked a little bit on hot days, as a sick joke. Whatever the actual story is, I’m starting to realize that the weirdest things happen to me.
