A good friend of mine once told me that if not for the fear of Allah, he would have smashed an old man whom he met on the road someday for what the latter did to him while he was a lad. 
He explained that the man was once a barber and anytime he was being taken to his shop to have his hair cut, the man would smite him because, as a kid, he (my friend) used to cry a lot.
Imagine what the brother could have done to the old man if not for Allah. If he had chosen to injure the man, he would have got off Scot-free because he (the man) had become feeble. 
I know that, just like the brother, we also do feel bad whenever we remember those who unduly objurgated us during our early stage of life. This is why you have to always rethink before maltreating the little ones because once you leave a scar in their hearts, it wouldn't be easy to erase. 
Abdullah ibn Amr ibn al-'As (May Allah be pleased with him) reported: Messenger of Allah (sallallaahu ’alayhi wa sallam) said: “Anyone who shows no mercy to our younger ones and does not acknowledge the honour due to our elders, is not one of us”. Sunan Abi Dawud (4943) Classed as sahih (authentic) by Albany
Trust me, some have lost their precious lives while some have been denied great opportunities all because of their wrong acts towards the young ones. This is because when the cheated young ones grew up, they haunted them down. 
Many of us are fond of this awful act but it is high time we dropped it and picked a beautiful one.
To earn their (children’s) respect/care tomorrow, you need to show them mercy today, brethren. 
May Allah forgive our shortcomings and make good deeds easy for us. Ameen.
