Thanks to Spectacular Six for pointing out that I haven't said anything about the girls getting glasses. Here's the story.
Tiffany and Katie had been asking me if they could get glasses. They don't need glasses, but Corwin & I both wear them (or contacts), and recently Tiffany's best cousin had to get them, so they wanted them, too. We've tried explaining what a pain it is to have to wear glasses and to take care of glasses, but they were not to be dissuaded (yes, of course we could just say no, but there's really no harm in it). So I thought I could just ask at the optometrist's office if I could buy the old demo frames when they were done with them. Well, when Katie's birthday came, we were at walmart picking up supplies, and the girls saw the optometrist's office there was open, so I went in and asked. Of course, they just send the demo frames back to the company. But the lady there told me I could just buy the frames right off the rack. The name brand letters come right off with a little fingernail polish remover. And they sell kids frames for as little as $10! So, I bought the two girls demo frames with demo lenses, and they were so happy. Surprising for me, Katie has taken really good care of hers, and she loves to wear them.
