Slang vs. Literal
According to Urban Dictionary, the slang meaning of “taking someone to school” is, “beating someone in a competition badly and thereby teaching them how it’s really done.”
Ahh, but what if that someone is your 18 year-old son, and you really ARE “taking him to school” — in this case, to college halfway across the country in the Bay Area?
Alternatives
“Dropping him off” sounds like he’s going to a friend’s house in the neighborhood.
Meanwhile, “delivering him” makes it sound like he’s a package.
Sometimes, there really are no words . . .
