The photo of Margret and Santa in the post below was from the year she wanted to give photos to friends and family for Christmas presents. She insisted that she didn't want Fred (what she called her portable oxygen setup) in the picture. It made Santa very nervous. Even though I assured him (and the camera gal) that her doctor had okayed 15 minutes off the oxygen, he kept reminding the camera gal that she needed to hurry.
It was a long line, a long wait, and I was more concerned whether her tank was going to run out before we got home. It did run out, on our way to the mall door. I had her wait at the door while I got the car. She climbed in, and settled down to relax on the way home. She was very happy with her photos, and not at all worried about her oxygen running out.
When we got home, I hooked her up to another tank, and had her sit in the car for a few minutes to let her oxygen saturation rise before she came in. She was fine. She was happy, and the happy was what was important that day.
