Doh! I lost my wedding ring.

One of my worst fears was realized today when I discovered that my ring went missing. I haven't lost anything in years, but I somehow managed to lose my wedding ring! I swear I took it off and placed it in the same spot like I always do. It's just not there. Now I'm second guessing myself. Did it slip off while I was washing my hands and roll down the drain and I just failed to notice? Or did it slip off when I tossed the trash into the dumpster? It remains a mystery and I am still pist.
