Grandparents are incredible if you're lucky enough to have them in your life. I never knew my dad's parents, but I was lucky to have my mom's parents in my life until my mid-20s.
My mom recently converted all her analog family tapes to digital, and my wife & I watched everything. My grandparents were always present no matter the occasion. I can't imagine not having that growing up, but I also think about how much more fulfilling things would have been if my dad's parents were also there. I wish they took better care of their health.
A future human may not feel as you do, but if you make yourself an excellent grandfather, they won't be able to imagine life without your presence.✌️
