21% said it was turning a blind eye to your partner's annoying habits, while 33% said it was important to know when to say you're sorry.

Kissing six times a week, surprise romantic gestures three times a month, and taking vacations twice a year. (I wonder if you have to take the vacations together in order for it to count...)
