The mother and the child are not smiling, but if you have a strong sense of observation:
See the child's cute little umbrella.he is loving the joy of holding an umbrella in rain but is not expressing his emotions.Going back from school he probably was so eager to use his tiny own umbrella that he forgot to carry his school bag.
The mother is walking beside him in the rain carrying his son's bag. She does not have an umbrella over her but she does not care. See where she is looking to learn why. :-)
Now, think about any moment from Your childhood that you can connect this worthless picture to. It does not have to be a rainy situation. It could be anything that performs the same love that you never noticed before up till now.
Stop reading, think !
Don't care about giving a like or not. Love your parents before its too late.
