unbelievable parenting

I realy cant believe some of the things i hear and see in this job.Now no one is perfect but isnt it a natural instinct as a parent to protect your chidren from harm you would certainly think so.This isnt the usual gripe of parents with the pushchair on the road while they stand saftley on the pavement waiting to cross or the other stupid action of putting children in and out of the car on the roadside instead of the pavement (cars have doors on both sides incase you dindnt know dohhh).What happened today was f###### unbelieveable. As i dropped my fare of and started to help the lady unload her shopping she left her child about 18 months old to wander around on the pavement and this was a realy busy road too while she messed about with her shopping, the child then wandered onto the road but instead of putting her shopping down and running to get her child like instinct would tell you to do she just called get off the road this child was too young to respond to orders like that and cars were getting nearer so i dropped her shopping and ran to retrieve the child who had now brought traffic to a standstill. She didnt bat an eyelid as i stood with her child in my arms an casualy carried on unloading her shopping.I was that mad and shocked i couldnt say a word,and if i did would she have listened you tell me
