Here is what the old KOOT should have done.
A) ask the mom if something was wrong with the kid & maybe she would get the hint.
B) Ask the mom permission to buy the kid a balloon or lolly pop to distract the kid from crying
C) Go to another line
Unfortunatly todays parenting skills are horrible by the younger gen.
The mom was prolly on twitter or meds.
With my 8 year old (Last Kid) I see a big difference in his class mates or scouts friends. Some of these kids are really coddled & whiney generation.
A big diff from my 19 year old son classmates.
The first problem is he was shopping in Wal-Mart, expect getto.
Second, rewarding a child with a ballon or candy is rewarding them for their unruly behavior.
