Valerie taught me this:
It's when there's a task you need to do,
and don't want to start--
So you delay
by doing other useful tasks
For example:
I need to make a phone call I dread.
So I clean windows,
sort socks--
I will do all those things I've been putting off...
all useful....
but not the urgent task I am avoiding.
Nice to have a name for something I've been
doing for years :)
