My Dad's a little like your's. Mum was very inclusive, and now that's she's gone my Dad is even more of a loner. Though he is my neighbour, if I don't make the effort to see him, he just does his own thing.
Which reminds me, I owe him a Father's Day lunch.
You are so right, they are called "loved ones" for a reason 😊
Hahaha. He will always be your dad, so you have to give him the best treat. Thanks for stopping by dear!
