India：

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.
不要在公共场合接吻。在某些地方你会因“公共猥亵罪”而被捕入狱（我们有许多条法律还停留在维多利亚时期）。尽管执法机关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 someplaces officially banned. This applies to both sexes.
不要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，穿着脚踝以上的服装都会引起他人不悦。

送礼时不要送偶数倍的鲜花，那是送给死人的，通常来说花束里花的数目是1/3/5/7之类的。
Don't criticize Soviet Union when talking with people over 40. They grew up at those times and might be nostalgic. Even if they enjoy modern life they might not like hearing foreigners talking about it.
