I find this thread lovely. My experiences have led me to believe no one notices kindness and that people see it as a weakness. I however treat others as I'd like to be treated and try to find and do at least one act of kindness a week.. Recently I:
Found a wallet with 600 euros in it on uni campus and returned it to campus security. It belonged to a Greek student who claimed it and it had been his family savings to help him at uni.
Bought a fleece for a homeless person who was old and wet, begging in the rain.
Took a suicidal member of staff for a coffee and time out, letting them know I would support them all I could. Despite them previously taking out a fictitious grievance against me.
Stopped a student from jumping down a stair well from the 8th floor. Then waiting with her until help came, she was schizophrenic and had not been taking her medication.
I'd like to be bold and suggest everyone try to do one kind thing a week, even if it's just telling someone at work they look nice. It's amazing how these small things can really pick someone up and make a day, week, month etc. Costs nothing and feels great to make someone feel noticed and or cared about.
