Last Friday，our class have a discussion about which to do during the coming holiday．Some are in favor of staying at home．They think it's both convenience and comfortable．Beside，they can save money for other purpose．But they will lose the chance of getting to know outside world．Others，on the other hand，would rather to go traveling since it can increase our knowledge．Therefore，they will spend more money and meet some difficulties while traveling．
Personally，I'd like to stay at home，for I can do whatever I like，such as reading books，watching TV，or helping my parents on the housework．
