Companion for Alexandra while I'm at work, Los Angeles

I'm Kevin, and I look after my wife at home in Los Angeles. Alexandra has failing eyesight and should not be alone for long stretches. I work nights, 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. Alexandra loves gardening 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 Alexandra present, and I'm happy to give a reference from the parish. If you have done care work before, wonderful, but kindness matters more. If this is something you could do, please write to me through the offer button.
