My teenager was headed to school one morning when I told him that the neck tag on his shirt was hanging out.

"I know", he replied. "It's a fad me and some of the guys started".

Weeks later, as the style persisted, I commented: "I can't stand it! Every time I see that, I want to fix it for you." I gently tucked the tag in place and rumpled his hair.

"Yeah," he said, smiling slyly. "All the girls do, too."
