Do you remember the first time you successfully tied your shoes? There is a sense of glory that comes from this small victory and I think it has a tendency to cement dates and times in the human mind. Of course, I could be completely wrong and perhaps this is only true in my singular, isolated case. It is hard for me to speculate on the topic since I never really discussed it with anybody. That being said, I recall that I first tied my own shoes, without any help, exactly thirty years ago today. It was a sunny summer afternoon and I was at my grandparents’ house for the evening. I never liked being there because they didn’t have an air conditioner, so my grandfather told me that if I learned to tie my own shoes, they would buy an A/C unit for their living room. So I studied all year. I focused harder than I ever have since because climate control and my own personal comfort were at stake. I figured that indoor air quality was as noble a cause as any. I only ever felt sad or angry while in a room that lacked air conditioning. I never wanted to feel those dark emotions at grandma’s house again. Sure enough, an HVAC system upgrade happened that year in honor of my “accomplishment”. My grandparents’ air conditioner thereafter made visiting them the wonderful time I always knew it could be. Though this climate control mechanism was not the best they could have found, I still thank the A/C gods every time I visit.
