3. Don't Point Your Feet at People
Feet are considered to be unclean and therefore it's important to avoid pointing your feet at people, or touching people or objects (particularly books) with your feet or shoes. If you accidentally do so, you should apologize straight away. Also, note that Indians will often touch their head or eyes as a show of apology. On the other hand, it's a sign of respect to bend down and touch an elder person's feet in India.
