Love is priceless. It's very rare to see. Those people are really blessed who could get and feel it.
At my son's school, a girl from KG1 called her dad at her break time from her mom's cell phone. She asked her dad to come. We know all kids do so. But unusual thing happen next... Within few minutes her dad came to school! Only because her daughter asked for it, he stopped all of his work and came to school. After few moment he left for his work again.
His wife told us, he is always like that. Sometimes from home if his daughter misses him and asked him to come, he drops his work and come back to home.
This is real love. There is no excuses... love will be always there whenever you ask for it.
