Supports; also endorses letting foreign students stay in U.S. after college graduation.

For Europeans, it's not uncommon to take a whole month of vacation in the summer. But the season can be a deadly time for the many pets left behind — permanently.

The abandonment of domestic animals by vacationers is a scourge in many countries across Europe. And in France, this summer isn't likely to be different despite campaigns by animal-rights groups against the practice.

We're not quite sure what to make of it. Is it an honor? Is it an insult?

Many of the key scenes in David McGlynn's striking new memoir, A Door in the Ocean, take place at the beach or in swimming pools. McGlynn was a surfer and competitive swimmer in his school days and still squeezes into his Speedos for races like the annual 5K "Gatorman" off the coast of La Jolla, Calif. Ocean swimming, in particular, transports McGlynn to another realm, and he does a terrific job of dramatizing the allure of solitary swims in open water. Midway through his book, he writes:

Kenneth Lonergan's critically acclaimed film Margaret was completed in 2006, but because of several lawsuits, it wasn't released until last year.

Called "nothing short of a masterwork" by The New Yorker, the film stars Anna Paquin as Lisa, a Manhattan teenager who tries to make sense of a bus accident she may have caused — one that resulted in a woman's death.

"Hey DOJ, we will go to the US. No need for extradition. We want bail, funds unfrozen for lawyers & living expenses."

"Detectives are investigating whether one of the heirs to the Tetra Pak drinks carton fortune lived with his wife's body for up to a week after her death in their Belgravia mansion in London," The Guardian reports.

Remember our reports a few months ago on the odd couple who struck an innovative compromise between egg producers and animal welfare activists? (Here's a hint: The deal calls for egg producers to replace their standard cages with new "enriched" accommodations, complete with perches and nest boxes where chickens can lay their eggs.)

The long economic downturn that began in late 2007 came to be known at the Great Recession –- the worst period since the Great Depression of the 1930s.

Even though both events were momentous enough to earn the word "great" as a modifier, they really are not comparable, according to recent research by economist Mark Vaughan, a fellow at the Weidenbaum Center on the Economy at Washington University in St. Louis.
