Is this the beginning of charity season?

My mailbox overfloweth.

I was out of town for a couple of days, and when I picked up my mail from the post office, there were 8 solicitations from various charities and non-profit organizations. That’s more than I can remember in a long time.

(Enumeration:
ACLU
another civil liberties type of organization
three different medical (red cross, heart assoc. and something I have never heard of before)
two university alumni associations
one non-profit publication wanting a donation)

Is it safe to assume that they’re all trying to pick my pocket as part of end-of-year contributions for tax planning?
