today i was pulling out of the auto-teller lane at my bank, right in front of me i see a 3-4 year old waddling through the parking lot and some lady almost hit him.
she jumps out of the car and picks up the child........turns out the child was following moms car which had just pulled out of the bank and was sitting in traffic after leaving her child behind...........
the lady who picked up the child ran towards the mom with the child.
the mom gets out of the car and sticks the kid in the back seat (no baby/toddler seat either) yells at the nice lady and speeds off.
i handed the moms plate number that i jotted down to the hero lady who had jumped on her phone.

what kind of person just forgets their child in a possibly dangerous location?
i don't have kids so this just baffles me and the only conclusion i can come up with is that the childs mother just didn't care or is a very very stupid woman...........
what should we do with these people?
has society forgot what's really important? or is it just a random occurance?
