Could you spend Wednesday and Friday afternoons with Silas? (Sacramento)

I'm Robert, and I look after my husband at home in Sacramento. Silas has failing eyesight and should not be alone for long stretches. I work until six, and the gap on Wednesday and Friday 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 5pm. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Silas loves old photographs 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 Silas present, and I'm happy to give a reference from our doctor's office. If you have done care work before, wonderful, but kindness matters more. Thank you. A few hours from you would make a real difference to our week.
