My dad is the most socially and physically active person I know. In his mid-seventies, his social calendar is still jam-packed: between swimming, playing guitar, and hanging out on the golf course, his lifestyle puts my own to shame. He also has a pretty serious heart condition that requires a pacemaker and a slew of medication. Fatigue can hit him during the day, sometimes making him unable to drive. I try to be caring without being overbearing, but when he has unexpected dizzy spells, I can’t help but voice my concern on the spot. He assures me he’s fine, that it’s not a big deal, and usually asks me to, “Please, just let it go.” I’m still fine tuning how to find the balance between offering help and knowing when to leave something alone as I navigate my ever-changing role reversal with my aging dad.
