making a fool of myself

I just asked the cute mechanic to come to our party. This is how it went down. I drove down the street, pulled over to muster my courage, called my co-worker because I saw him get out of a car and cross the street after which I felt hugely dorky because I knew he could see me sitting there, and knew it was me because my car is pretty distinctive. While I'm on the phone freaking out, he comes over and asks me if I'm bringing my car in, I turned beet red I'm sure, hung up the phone and asked him to come to our party. He actually sounds like he might come, and now I'm embarrassed.
