when you are the son of a company owner, you are capable of doing anything. This is exactly what happened here, some of my inflatables are stored in a mezzanine that my dad made in the factory where I work since they don't fit in my house and inside a box I left a bag with 2 or 3 Sisu balls that are to sell.
An hour before the end of working hours, my dad went home and I stayed there thinking about doing something I had never done before. I took one of the sisu balls and started playing with it on the mezzanine so that no one could see me, I felt a little strange but I liked it.
