it's rude, it's un-acceptable.
welcome to hollyweird run by A types who get off on dumping on people
below them as free therapy.
in the past i have followed up each sub with 1 call after a week,
another after 2 and a last one after another two- a mercy call.
people get busy, if they are producing, they probably will not read
for months. how you leave off depends on how important the
relationship is to you.
at times someone blows you off one year and the next year, when they
are between pictures they become your bestest buddy.
rule of thumb: never close any doors in this biz, too few open as is.
best,
zack.
