A survey has found that they are one of the most common causes of fights between British couples.
The poll of 2,000 adults discovered that only rows over money and disputes concerning household chores occurred more frequently than bickering about each other's relations.
The study by electronics firm Philips found that poor budgeting and a lack of savings regularly cause couples to fall out, as does women being lumbered with too many domestic duties.
The top ten reasons also included drinking habits, hoarding objects, doing the washing up, deciding what to watch on the TV and the time it takes to get ready.
Researchers also found that one in ten of us have a fight with our partner daily, while one in twenty has several fights per day.
"Couples will always argue. Even trivial things - like who looks after the TV remote, leaving wet towels on the floor and taking too long to get ready - rile us," the Daily Mail quoted spokesman Deneice Harwin as saying.
