That is such fabulous news! CoNgRaTuLaTiOnS!!!!
My dad just retired at the end of August, and he, too, was somewhat apprehensive about what he was going to do with his time, as he's been working full-time since he was 16!
But, after the reality of retirement set in, he has not had any trouble finding fun things to occupy himself with. Good luck to you as you begin the next phase of your life with your little companion Max! I know the both of you will have a BLAST!
