I remember how confused I was as a child when someone would say “nature’s calling” and then they’d excuse themselves. Only later did I find out that it was a silly euphemism for “going to the bathroom.” It was also silly because I never used to believe in spirits, God, mother nature, or anything beyond what could be measured/verified/scientificied (not a real word). I was an atheistic and didn’t really know what the purpose was of this life we all seemed to get plopped into.
I’ve since changed my tune for reasons that are too numerous to list here. Now I’m a believer in signs. Now I believe that (somehow) people, events, or situations appear at the right moment to guide us along our purpose in life.
