A kind person to sit with my mother on Tuesday and Thursday afternoons in Munich

I'm Hans, and I look after my mother at home in Munich. Lea has Parkinson's and should not be alone for long stretches. I work long days at the clinic, and the gap on Tuesday and Thursday afternoons is the hardest part of my week. What I need is someone calm and reliable to be in the house from about 12.30 until 6pm. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Lea loves cricket and will talk your ear off about it. I'm home before dark and will always leave the phone numbers of the doctor and a neighbor. I'd like to meet you first with Lea present, and I'm happy to give a reference from our neighbor. If you have done care work before, wonderful, but kindness matters more. I'll be so grateful for any help at all.
