People from various countries share customs that are totally normal there, but weird everywhere else.
The best part about the Internet, besides seeing idiots humiliate themselves on Facebook, is having the opportunity to learn about places and people without ever having to leave the bathroom.
Despite all this inter-connectivity, each country still has its own quirks that are commonplace there, but would seem totally bizarre anywhere else. For example, here in America, it's perfectly normal pick your teeth in public with one of those floss picks and leave them on the ground (or at least that's what my deskmate would have me believe). Today, the people of reddit shared the uniquely weird things they do in their countries.
