Some people feel the need to ridicule others to ease their conscience because they are not interested in health or improving themselves- it's an easy way out for them.
I'm at work one day- bring my lunch everyday- 2 girls walk in & say "What are you eating?!?!" (I'm having a plain chic breast & cucumber slices) One of them has a Klondike bar & the other a bacon cheeseburger.
I said, "What are YOU eating?!"
and they accuse me of eating 'weird food'. (?) At least I can pronounce the ingredients.
