In Pakistan, families are considered sacred and arranged marriages are common. When marrying, the daughter-in-law moves into her husband's house. If invited to someone's home, it is proper to bring a small gift like flowers or chocolate. Men should avoid giving flowers directly to women and instead say the gift is from a female relative if giving one. Pakistanis are skilled negotiators where price is important, but they aim for mutually agreeable deals. Discussions can be lively and switch to Urdu, so remain calm. Pakistan hosts the world's largest volunteer ambulance service and makes most of the world's soccer balls, and contributes greatly to UN peacekeeping.
