11 year old asks his Mom: “what’s that funny sound” (telephone busy signal…)
An 11 year old boy called a friend form his home (wired, POTS) phone, but when heard an unfamiliar sound he asked his mom what the “noise” was. She explained he was hearing a BUSY SIGNAL. Almost everyone has call waiting (or uses a mobile phone) so the young man had never heard a busy signal. We live in interesting times.
