85) Confusing Morning

I had a confusing morning and am not sure exactly how it happened. I woke up and went through my routine as I do every morning. I brushed my teeth, put my contacts in, got dressed. As I washed my face and messed with my hair I noticed that my right eye was a little blurry. I adjusted the contact several times, but the blur never cleared up. I took the contact out and looked at it closely, thinking that I must have put it in backward or something. The contact looked strange, almost like it had split and had two flaps going in different directions. I was not quite awake and could not see so good, but I played with the thing until I realized it was actually 2 contacts stuck together. I looked at my contact case and realized that I just came home from vacation and opened a new package of contacts the day before. My thought was, I must have left the old contact in the case, and then last night put my new contact in the same case. So I pulled the two contacts apart and tried to determine which was the old and which was the new. I could not tell them apart so I blindly chose one and decided to keep the other one in case I learned today that I was wearing the old one. I continued getting ready, made my lunch and then went to find Liz to say goodbye for the morning. While talking with her I felt like my left eye was blurry and immediately assumed that I was wearing 2 contacts in my left eye. By this point I was running a little late, so I hurried to the bathroom to dig out the 2 contacts and see which was the older. I peeled my eye lid back and could not see a contact. I felt around in there and discovered that I did not have a contact in my eye. So, I went to my case and took the other contact out, the one I thought was older, and put it in my left eye. I guess this morning I put both of my contacts in the same eye. This is the first time I have done anything like this. Has this ever happened to anyone else?
