Does anyone have a retirement gift idea?

My grandmother who is very special to me is just retired from her job. I'm going to see her soon and need gift ideas fast.

She doesn't like to leave her house unless she has to. Not even for eating or shopping so no gift card. She isn't going to be traveling at all. She is overweight and food gifts are out. She doesn't have any hobbies that I can think of. Really all she did before was work, sleep, and watch television. I don't know what she will do now. Her house is so filled with things I cringe at the thought of buying her something more to decorate it with. She doesn't need or want clothes or jewelry. I have about $70.

I have no clue what to get her.
