I was pg during the Susan Smith case, and I just knew she had done it. I'm not sure why.
The glasses thing, to me, doesn't mean much. Before I had LASIK, I wore glasses or contacts. Sometimes I just didn't go to the trouble of putting the contacts in, even though my vision was better with them. Also, people are far or nearsighted, (or both in my case!) so that may affect why people put on/take off glasses. I just had LASIK again on one eye, and prior to that, I had a pair of glasses that I wore depending on the lighting. If it was dark or hazy, or poor lighting, I had to have them on. But if I stepped outside into the light, I had to take them off. It was quite annoying, which is why I had the procedure done again!
