Q.3.3.1 Dimpho is 16 years old and sees that his neighbour, Sally, has advertised his Mac Airbook for sale for R7 000. Sally and Dimphos mom have been friends for years and are in the same bookclub, amongst other things. One day while his mother is out, Dimpho goes next door to Sally and tells her that his parents have given permission for him to buy her laptop and that his mother will go over to Sally to pay her the following day. Dimpho is hoping that once he has the laptop in his possession and owes the money, that his parents will be too embarrassed not to pay Sally. Sally allows Dimpho to take the laptop with him as she has known the family for years and trusts that she will receive payment. In his excitement, Dimpho takes the PC to a friends house to play on. While there he goes to the bathroom, leaving the laptop temporarily unattended, his friends two-year-old brother messes a sippy cup of juice across the keyboard and the laptop is damaged. Dimphos parents are furious with him and refuse to pay Sally for the laptop. Dimpho is forced to return the broken laptop to Sally.
