At 72, I am retired but still run my beef cattle farm in the country. I have a TV but I can't get reception our here in the woods.
I also have full-time custody of my 2 year old granddaughter after her parents died in an auto accident a year and a half ago. She has no one else. My wife passed away a year ago from cancer. Between the farm chores, and maintenance and raising my two year old, I have no time to watch TV anyway, so it works out.
I also have no use for Twitter or Facebook or Instagram or whatever either. Not everyone follows social media, especially at my age.
you can watch TV via the internet. your local library might have access to streaming hoopla and Acorn TV for example. There will be things your grandaughter can watch.
I use both hoopla and acorn TV via library membership and have slow internet access.
God Bless You HotHunt!!! Prayers for daily strength!
