It's the sort of traffic jam I like to see.

Our annual fund-raising campaign on behalf of Children's Hospital is attracting group gifts by the bushel. I can tell in two ways.

First is the long list of group givers that follows. You're the best, troops. Well done.

Second is the long looks I start getting at this time of year from the hard-working souls in The Washington Post's mailroom. The rest of the year, we're buddies. During the winter holidays, they start looking at me as if I owe each of them a new set of back muscles.

Sorry, mail gang. Just know (and tell your backs) that all those heavy baskets full of envelopes are for a very good cause.

By the way, if any of you readers haven't yet made a donation to our 1999-2000 campaign, may today's column serve to beckon you.
