Grandma is my last grandparent standing. I mean, I have Grandpa Lyzenga, but I married into him when I was full grown rather than having memories of walking with him when I was tiny; and as much as I will sometimes introduce Aunt Ellen and Uncle Phil as my Lingen grandparents, and as much as they are doing their darnedest, they are in fact a really really special great-aunt and -uncle, which is its own thing and not to be denigrated.
But Grandma has enough personality for four grandparents all by herself. (So, I know firsthand or hear quite vividly, did each of my other grandparents in their own ways. Lack of personality: not an issue in this family.) Grandma is an Energizer bunny. I wrote in her birthday card that she embodies the adage about blooming where one is planted, and I really think that's true. She does well with new people and new situations. She just dusts herself off and tries again, whatever she needs to try again, and I have never once heard of a situation she couldn't eventually make that work in. Never once. Her persistence inspires me. I hope it lasts long past 80.
