I've met those people couple of times. Luckily I have never been forced to be taken into a foster home or nothing even close to that. My family has been pretty lucky with that thing even when times have been tough.
But still, regardless of this, they've always felt as if they are just doing an automated job; asking the same questions, forcing to do the same things etc. They have no feelings, they only work.
Oh and they don't understand the phrase "I don't need your help."
thanks for your feedback @dromzz.. the more people that share their stories the better here!
