from ABC news. Mark Kelly talks about his wife Gabrielle Giffords playing with his wedding ring.
I'm pretty sure she does and certainly today.
What convinced you?
Yesterday in particular she started playing with my wedding ring. So if I hold her hand she'll play with my wedding ring. She'll move it up and down my finger. She'll take it off. She'll put it on her own finger. She'll move it to her thumb, and then she can put it back on my finger. The reason why I know that that means she recognizes me is because she's done that before this accident. She does that all the time.
