A time to let your hair down.
Strange, when i tell you parties like this are almost always organised in super secrecy. Outdated attitude of the mullahs towards these hip youngsters totally pisses out the x generation of today. There are no written laws about parties. Just that fun and togetherness in the open is jealously hated by a certain sect in the ruling community. It is also common for many parties being disrupted abruptly by police.
