Do HARSH words need to be returned in equal or more measure?

Divyaa - you ain't a mother so you would'nt know!

Ah! To be dealing with kids I don't need to be a mother at the first place .....and dealing with 30 odd kids in the last 3 months helps me understand their PSYCHOLOGY well too....

Today a parent happened to discuss with me about discipline lessons through shlokas....

Parent: My son would never listen....Its going to be hard on you Divyaa, really hard!!

Me: Dont worry...I will take care of him in class...

Parent: Your not a mother, you don't have kids ...so you would'nt know...

Me: Taken a back.....(A few things can be said in better ways --- maybe she did'nt mean what she said...but it did hurt me)

Parent: We know our kids better

Me: In class.....I deal with them...So I sure know how to deal with them and in class all the kids listen ...so your kid would follow!( (Smilingly walked away)

I personally feel that HARSH WORDS don't have to be returned in equal or more measure....I just walked away - my way of dealing with it:)
