DEAR ABBY: Two of my granddaughters have posted pictures on Instagram that show them facing away from the camera with their bottoms covered and their tops nude. They said this is part of the "Topless Tour." They said it's no big deal because it only shows their back and "everyone does it." I feel it is inappropriate to post something like this on social media. Will you please share your opinion? -- GRANDMA IN UTAH
DEAR GRANDMA: I think it's unwise, but the times they are a-changin' and along with them, the current fads. The Topless Tour -- photos of topless women shot from the rear in a scenic location and posted on social media -- is just another one of them. Calm down and thank your higher power that this fad is tame. At one point, people were lowering their pants and "mooning" passing trains and cars.
