I got caught.
I was driving down the road singing my little heart out. A number I do not know calls me. I check the voicemail Mister Anonymous leaves. He says, "I guess you don't want to answer your phone. I see you in your car." YIKES! I call Mister Anonymous back right away and ask him to reveal his true identity. Apparently this guy (whom I do know) saw me singing my little heart out and was so amused he wanted to call and tell me how much I looked as if I were enjoying myself. Embarrassing:-)
