I saw this printed on a roadside billboard recently: "No matter what scale we use, we never know the weight of another person's burden."
Pretty heavy and oh, so true. When Mom passed away, I jumped in the car and started out on the 8 hour drive to their home. Stopped to gas up and grab a coffee midway - the cashier was pleasant and handed me coffee, change and "have a nice day". I thanked her and thought ,"You don't know I'm on my way to my parent's home, one will be missing. I really need a hug."
Recently a friend of many years phoned me to meet for coffee - his wife of 40 plus years lies in hospital - terminal. We hugged as we met, sipped our drinks, tears sloshing around our eyes. The shop was full of people - if anyone did notice us, they would see only a man and woman occasionally laughing, talking and having a visit - but what a visit.
I have determined that everyday, I will be more compassionate and show the compassion, to everyone - you don't know the weight of a burden they could be carrying.
