I taught an old man at the grocery store how to spot ripe avocados. I don't know what came over me.
He was definitely over 65 years old, and I saw him picking through avocados with a concerning, almost overwhelmed look. I guess I was in a good mood because I approached him without any anxiety or thought and said, "hey, you want to know a trick?" He looked up at me, I picked up an avocado, "if you remove this little knob here where the stem grew and it's brown.." I removed the stem knob and it was brown to my surprise, "then it's likely brown inside and bad" I picked up another avocado and continued, "if you remove the little stem and it's still green" by god I picked a perfect avocado again, I showed him it was green, "well then it's perfectly ripe".
A big smile now on his face, he said, "hey thats pretty good!" Thanks me and I go on my way.
I smiled the rest of my shopping trip. I hope I spread some community vibes in that moment.
