I only knew my maternal grandmother. She lived to be 96, and lived alone until she had a minor stroke at age 90 and my mom basically made her come live with us. We liked to go shopping together, and eat at the food court together. But some of my favorite memories of her are from amusement parks. Until she was in her mid to late 80s, she'd always take us to Six Flags once a summer. She mostly went on the calmer rides (Like the carousel, Ferris Wheel, and log flume,, but loved Thunder River, the "river rapids" ride. She wore a wig. To keep it form falling off, she would sit with one hand on top of her head the entire ride. She also let out this long, drawn out, "wwwwwhhhhhhoooooooooppppppppssssssssss!" every time we'd hit a rapid, bump, etc. We'd all be cracking up (including her) and the other people on the ride with us would just kind of look at us the first few times, but by the end, she had the entire boat/raft laughing at her "WHOOPS!" She was mostly steady on her fee in those days, but with that, by the end, she'd have trouble getting out of the boat, mostly because she was laughing so hard at herself. I'm sure the other families on our boat/raft told stories of the crazy lady who had her hand on her head the entire ride. Great memories.
There was also an older man at my church that basically anyone under the age of 40 called "Grandpa." He helped with the youth group and was well known for his kindness and his hugs. Sundays just weren't complete wihtout a hug from "Grandpa." Can't wait to see both of them again one day in heaven. He wasn't my blood grandpa, but since I never met any of my biological grandparents, he was just about the closest I had. So I count him in "grandparents."
