One if my good friends is visiting her elderly (88 year old) mum regularly because her mum is lonely. She's going with her 16 year old daughter every time. Her daughter goes between her and her dad's house twice a week as well. Of course none of my business but I don't want her mum to get it as I'm fond of her and I've said I think she shouldn't visit and ideally her daughter should choose between houses or at least swap less often.
I know I'm being judgemental but we're (my family) in a high risk group and I can't understand how anyone can be so selfish.
