Comment on my hair cut

Yesterday I went to school to get my daughter from school. Couple of days before I have done a hair cut on someone in school, but not seen the person ever since.
So I asked from few mums around what did they like about my hair cut. I asked Debbie: " Did you see Janes hair?" Debbie answered with an angry voice: " YEAH! " I was slightly confused, thought that Jane did not like it and asked Debbie: " Why, what is wrong? "
And Debbie said to me : " I liked it better when it was long!"
But Debbie, IT IS NOT YOUR HAIR!!!!!!

Some people, they are unhappy, even for someone elses hair cut.....
