Trouble recognizing people?

[Klompy]

I'm starting to wonder how much I suck at observing things in general, especialy recognizing people. Today two things happend to me that showed me I'm horrible with faces. At the bank, a girl about my age came up to me and asked how I was doing, and that it's been a long time. I had no idea who she was and tried to play it off like I did. Then tonight I'm watching TV and see This comercial come on TV again. I've made fun of this commercial several times in the past to friends, but today I figured out that the soldier in question actualy went to my high school (small school so everyone knew everybody). In my defense he looks a lot different now then he used to, but both of the parents were involved in a wedding I stood up in about 6 months ago. How the hell can I watch something like this so many times and not see this?

Is anybody else horrible at recognizing people? I find it causes tons of awkward spots in my life, and I'm curious if this is normal.
