CHILDHOOD FUN BACK IN THE DAYS
Justification:
My caption stems from the fact that, back in the days, kids often go out to play with other kids and create a form of bonding and, buiding sand castles happened to be one of those ways kids had fun back in the days. But with the advent of electronic gadgets, kids no longer have fun this way, they stick to their gadgets and miss the fun of physical bonding which comes with playing with other kids and building sand castles.
