Ah, I see what you mean now, the very time time I should take something literally..! I think I can understand that itwould be easier than talking to people directly but I worry that would come off as rude to some people? My brain tends to over think things like this though, often to the point where I get it completely wrong! Thinking about it, my lack of eye contact and mumbling probably comes off as a bit rude too. The important thing is that it helped you. It seems that you were lucky enough to find a workplace where you were able to do that, work really does help people in so many ways. I often learn by imitation, watching how others react to situations.
Anywho, I guess that work is a huge boost for self confidence as well as general life skills and being out of work could have a negative effect on them. Again, it's about that balance that you seem to have gotten the hang of better than I have.
On a side note- when I'm at the supermarket I find the 'scan as you go' really helpful; I can check prices of things without asking staff, I can already see what the bill will be before I go to pay (my maths skills are appalling) and I can put everything into the bags as I'm going atound which means that I don't get in a flap at the checkouts. Then I just scan the barcode, pay via card & go home. Zero human interaction providing other customers leave me alone.
I seem to babbling again, apologies if I have.
