Companion for Sergei while I'm at work, Karachi

I'm Zoya, and I look after my father at home in Karachi. Sergei has failing eyesight and should not be alone for long stretches. I work part-time at the shop, 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 2pm until 5.30. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Sergei loves his allotment 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 Sergei present, and I'm happy to give a reference from our neighbor. 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.
