It’s unfortunately rare for someone to express their sincere truths to you or to act overtly considerate.
Lots of acquaintances will disregard you, fail to give you the time of day, or just ignore you.
Or people will be flakey.
But some choose to be considerate and thoughtful.
If you remember they were sick and let them know you hope they’re feeling better, instead of “thanks” they will say “thank you for thinking of me. I am doing better. I hope you’re holding up okay too.”
It’s easy to be consumed with ourselves. Be the example and show kindness, especially when someone else is.
