回複：大家說該怎麽辦？一件發生在溫哥華的真實的事

you have to be really careful to live with a person like that, keep eye on your own money. If you are going to live with him while also wish not fight over the money on daily basis, you can try the receipt policy: each person keeps the receipt for the things you buy, at the end of month, do a balance, the person paid less write a check to the person who paid more. It sounds like business, but really works. it also helps the family to keep track and control the expenses.
