Today I was walking down the road with a water bottle in my hand which I purchased from the last 20 bucks I had.
A lady with her small child (around 4-5 years old) was selling balloons in the corner of the seats asked me for water. (The temperature was around 38 degree Celsius.) I simply walked over but I don't know what pulled me back. I just stopped, went back and poured chilled water in the glass she was carrying.
The look in her eyes was priceless.
I walked away after doing this and I realized later that I could have offered her more water. :-| But anyways this simple act made me very happy that I was able to make a stranger happy with what I had at that moment. I felt blessed.
