So, ya know, don't ACTUALLY going around spanking strangers but I am almost certain you saved any NUMBER of moms and their kids from getting nasty comments from that lady again.
I envision the woman's exchange with friends later going like this: "Her son was just out of control, so I told her he needed a smack...and then she shouted at ME that I should be smacked and put her FINGER in my FACE! No wonder her son is so out of control, she has no manners either!"
....not "You know, she was right and I shouldn't have said anything to her. I don't know what was going on with her day, or her son."
If it was that easy (i.e., dish back what they dished to you) to get a rude person in public to reflect on their actions, we wouldn't have so many rude people walking around.
And yeah, I'm creeping up on 40 and can't imagine being called "elderly" in 14 years. : No matter her age, she was rude and acted poorly.....but acting back in kind doesn't really do anything to further the cause, you know? Again, standing up for oneself against rude behavior with a blunt, calm, confident comment or even some calmly delivered snark, sure - but I'm not getting the kudos on the thread, either...
