What are the top 3 things you fight about as a couple?

MONEY, CLEANLINESS, THEN MONEY AGAIN I hate it when he complains I use the toilet paper wastefully when he smokes $300/mth and buys breakfast for his colleagues without them paying him, while I scrimp and save and don't dare to order anything when we eat out, pretending I am not hungry. I feel he is v silly to b "cheated" by his colleagues
