Tuesday’s back, by popular demand.

The sun, however, might be hiding today. It’s 7 a.m. and 44°, heading to 59°. And it’s going from partly cloudy to mostly cloudy, though we all know how the sun likes to hang out in the Mission.

The Chronicle reports today on how Mayor Lee is planning to make San Francisco a city for the 100 percent.

A coalition of health and education groups released recommendations for sex education that are controversial for some, reports the Associated Press. An excerpt:

Finally, what dog lovers have known all along is reported in the New York Times today: Dogs are like furry infant humans. From the article:

“Being in a human family gives the dogs the ability to interact in a human way,” Dr. Miklosi said. “You can really treat your dog as a sort of infant, which you wouldn’t really do with a goat or another domesticated animal.”

Maybe someone will do a study showing that cats are like adorable, ornery toddlers.

Happy Tuesday, friends!
