This week is a big one is our household because my wife’s last day of work is Thursday. Yep, after 31 years with a major company that is well-known around the world, she’s retiring. To say she’s looking forward to retirement would be an understatement. She worked hard to be a highly valued employee, but she’s ready to move on to the next phase of her life.
Although the week will end with our wedding anniversary, this post is a salute to her retirement – which also means I’m preparing another salute to a different number.
Life will be an adjustment for both of us, but we’ve been a team for a long time – so the new available time should be fun. A tip of the hat to my partner in life – the one I’ve loved for a long time.
