I found, somewhat to my surprise (although once I thought about it, it shouldn't have been) that I couldn't cope with working around what had been 'my field' (unlike storynanny).
I wanted to deal with stuff I saw, but it wan't in my remit. I wanted to share my experience - but it was less relevant in today's world (I live in an area where only statutory care is being undertaken, so advice has to be tailored to that). I felt frustrated on all sides.
So I have ended up volunteering out of my field, and the new skills I have learned have been interesting. I have developed skills that were previously just a hobby.
I agree about expenses - they must be handed out. Being in a fortunate position, I have saved mine and bought raffle prizes with them.
I volunteer with a small arts festival and as a member of the committee, I get free tickets. I also have a position on our village hall committee, where until recently, we were expected to pay for tickets to social events. Some members felt strongly that we shouldn't get 'freebies'. I became aware of one member who would help, say cooking cakes or similar, but might not turn up - there might have been many reasons, but I wondered if he couldn't easily afford the ticket. I said nothing to him or others, but suggested that 'working' committee members should attend the social events for free. After much wrangling, half price was agreed on.
I'd also add that since my arthritis has worsened, I am much better at doing things like publicity, or book-keeping, as I can do that in my own time, and don't need to worry on a 'bad day'.
