You have three children and when the eldest is 17 he tells you his 15 year old girlfriend is 6 months pregnant but still doing gym lessons at school and then the second one when she is 16 says she wants to move in with her 19 year old boyfriend and get engaged and have a big party and then the youngest decides at 16 that college is an option but only if he can stay in bed til lunchtime but he gives it up after 2 years because he is bored and the state stop all your WTC cos you no longer have any kids in fulltime education so you carry on in your full time job until the dementia kicks in.
