Because I'm not!
Today bumped into a friend (s) and her friend (a)-who I've met socially once or twice, was pushing ds along in the pram and they both waved hello. A booms 'bloody hell! You're SUCH a dwarf! Youre bloody tiny pushing that pram, bit tall for you isnt it!'
Fwiw I'm 5 ft 2. I know I'm small but there is absolutely nothing wrong with me. I fricking hate people commenting on my height, just find it knocks the wind out of my sails and its downright rude.
I was brought up to never comment on someone's appearance unless it was to compliment. I wish is was a rare occurance but it was practically every day through school/uni and about monthly now.
