India：
在印度：
Kissing in a public place. In some jurisdictions this can get you into jail under "public obscenity" (a lot of our laws are stuck in the Victorian era). Although the law enforcement cuts some slack if the couple is married, if the couple is unmarried things can get really messy.
在公共场合接吻。在某些司法管辖区，你会因此以“公共猥亵罪”而被捕入狱（印度有许多条法律还停留在维多利亚时期）。尽管执法者会对已婚夫妇从轻发落，但是如果是未婚情侣的话，事情就会变得麻烦起来。
Shorts/skirts in a place of worship. Dresses that show anything above the ankle is generally frowned upon in most places of worship and in some places officially banned. This applies to both sexes.
在礼拜场所穿短裤或短裙。在大部分礼拜场所以及官方明令禁止的地方，不论男女，穿着裸露脚踝以上部位的服装都会引起他人不悦。
