This is a lovely thread. 
I’ve often been guilty of daydreaming of winning a sizeable amount on the lottery. My plans are / were to give substantial amounts to my children and grandchildren, then family and friends. I’d love them not to have money worries and to be able to treat themselves. I’d have to keep adjusting the amount given in my mind as I’d think of others I’d have to treat ie charities and wanted to make sure I had sufficient left for my own needs...but I never really thought what I’d spend on myself and my wants!
In the spirit of the thread, my first gift to me would be to have (Covid aside) full dental works. That would cheer me up no end. Then I’d look towards sharing my good fortune. Next, I’d look for a nice place to live in the U.K., a new car (not a flashy one, just a nice new one) and then a little place in Spain, not too far from the sea but inland, in a nice village or town. It has to have a nice roof terrace with a view of a castle lit up at night whilst I’m sat sipping my vino. It also has to have sufficient garden / outside ground floor area for my dog to run in and out, who will have a rescued companion to live with. Oh, my bedroom has to have access to a little terrace.
I can but dream
