A week or so ago I attended a reception to thank major contributors for the thousands of pounds they had raised in 2016. They included people who had done sponsored skydiving, zip wiring or running marathons, so I felt very humble having personally only raised a three figure sum. On the other hand I had helped organize & run an annual walk at which hundreds of participants had chipped in with a fiver or so, resulting in a total every year to match the one-off daredevils.
