I have a serious topic I would like discussed, so please, may I have your fullest attention. I have a useless, waster of a sister in law. She tips the scales at 23 stones, and is, how shall I put it? Um, rather in-active. She is currently suffering from her 15th chest infection this year!!!!! She has a small son, my nephew, who is 9 on sunday. He cannot swim, he cannot ride a scooter and, are you ready, he can't ride a bike I have offered to get him a bike for his b'day (he needs at least 24"), not a new one, but either salvage one from the tip, or get a second hand one. I have offered to teach him to ride it, but S-I-L thinks it is too dangerous to ride a bike nowadays because of all the traffic on the way to school, so she drives him (I know, I have pointed out she is a contributory factor). My wfe has offered her sister her old bike, so they can essential learn the skills together, but she was sworn at for taking the piss We have tried cajolling, being blunt, being supportive, pointing out the health risks and are now quite frankly stuck. I was thinking of getting my nephew over for a sleepover, and just damn well teaching him, but my M-I-L thinks S-I-L will go ballistic. Any suggestions?
