Patient discussion about expression

Q. where do the expression "going back on the wagon " come from?

A. http://www.phrases.org.uk/meanings/on-the-wagon.html

Q. What role does emotion have in the life of someone with autism? I just find the whole disorder of autism hard to understand because I'm a really emotional person. I'm especially interested in how people with mild autism or Asperger's can function fine but then when it comes to feeling empathy they have such trouble. I guess my question is how such people experience emotion--are these people actually unable to care about others? My intention is not to sound ignorant, I'm genuinely curious.

A. I have asperger's and most everything for me is logically analyzed and I have a difficulty knowing what emotion goes with certain situations and how the emotion manifests itself within me.
I care about others, I just cannot always put myself in their shoes and feel what they are feeling.
