Doctors are encouraged that Gabrielle Giffords is interacting so much with her family and caregivers.
She is clearly aware of her surroundings and is interacting with gestures, Dr. Dong Kim said.
During the trip from Tucson, Giffords was tugging at a ring worn by UMC nurse Tracy Culbert. Culbert said she took off the ring and handed it to Giffords, who held it up and looked at it closely. Then Giffords put the ring on her own finger and wouldn't let anyone take it off.
Culbert said she'll miss her famous patient.
"I'm very lucky to know her and to know her family," Culbert said.
