At age 2.5, my middle child used to complain every time we were on the freeway that the freeway made his back hurt. So, we'd hear, "The freeway makes my back hurt. When are we getting off the freeway?" over and over again, until we exited. Sometimes, we would try to convince him that we were really on side streets even though it looked like we were on the highway in the hope that he would quiet down. It never really worked.
