Hi Rumpleteazer, Even though you're cleaning up after cleaning the ceiling. You & your family sound very sweet
Your Uncle is clearly the black sheep in your family, and it is truly his loss. I hope one day he can see what he has lost, and perhaps make amends to you.
Like the Poet, Robert Frost has said " Family is the one place, where they have to take you in " Sadly some make that very difficult indeed. I hope it all works out for you.
