Once, there was a father walking with his two children ( 12yo and 9yo) in the street till they arrived home, then them father told them to build a big enough wall near them house, the kids replied by saying we can never build that wall ..! Then the father obliged them to build them, it took them a year and a half to build that fucking wall ! At the end this two children's dad told them DONT YOU EVER TELL ME AGAIN THAT THERE IS SOMETHING THAT YOU CAN'T DO !
