Back to the era before internet.
If popular social network nowadays are facebook and Twitter. In Indonesia the popular social network was Citizens' Band Radio (CB Radio)
http://en.wikipedia.org/wiki/Citizens'_band_radio
There were two Wave Length, 11 meters and 2 meters. But 11 meters was the most popular, 2 meters were used only by 'serious people'.
People used CB Radio to chat in the air. They also made many chatter groups, even certain groups had moderators like forum. But different than forum, CB chatter people sometime meet 'off-air', in gathering or in dating. No wonder if some people called CB Radio as "the good tool for people who want to get spouses". But same like in internet, in CB Radio world, there were some fake chatters, ages are over 40, but pretended like early 20's people to attract opposite gender.
My senior colleague was CB chatter. He meet in the air with a woman who called herself "teteh" (older sister). He thought she's only few years older than him. However, when he meet her in gathering, he's knew if that women age was almost same with his mother.
But this is not the end of the story because finally he knew, that woman has a daughter. That's why, when he told this story, he said "I was chatting in the air with my mother-in-law".
