My mom and dad.
Some of you know the story... they met at a bowling alley (they had the same last name BEFORE they were married); they were bowling and the guy says "Stadler (not our real name), Lane 2" and they both showed up, met, married like a year later and were together for 58 married years, spending 24 hours a day, every day, with each other until my dad died in June. I had to tell my mom and she just looked at me and said "I lost my buddy." He got severe rheumatoid arthritis at a young age, about 35, and was for all intents and purposes, physically handicapped the rest of his life. Two artificial hips, four artificial knees and set of new knuckles on one hand later, he managed to make it to 83. The list of other things he battled - he beat non-Hodgkins lymphoma twice, had a partial bowel resection, had Joe Montana spinal fusion, numerous small bouts of skin cancer, and heart disease - is something, but the lesson is...
They never quit. I never once heard him say "why me?". He always counted his blessings, not his curses: a brain that worked (he's the smartest guy I know; he made me feel dumb, and I'm in MENSA), a loving, beautiful wife, two decent kids, an extended family that loved each other, even if that love was sometimes flawed. He taught me you play the cards you're dealt, don't waste time wishing for cards you don't have. He taught me you keep plugging every day. EVERY DAY. I used to have to put his socks and shoes on for him because he couldn't bend (and even if he could, his fingers weren't dexterous enough to tie the laces). Mom taught me that we're greater than the sum of our parts. She taught me that you make a commitment, you keep it. That THIS is your life; not the life of others you see on TV or Instachat, but this one. Mom's now fading at 85, and in memory care, but both of them lived with no regrets and with pride for what they accomplished. Not a moment wasted on worrying about what they didn't.
They weren't perfect, far from it, but I got all the life lessons I ever needed from them, and I'm grateful every day for that.
