What are the three things that annoy you most about people? Characteristics that you don’t want in a future spouse. It could be something as simple as leaving the toilet seat up or a person who when reading a book reads out loud.
I for one, would not marry someone who isn’t ambitious and is devoid of an iota of self-drive. Or someone who doesn’t keep their house clean and tidy. And i’d especially not marry someone who is unfamiliar with personal hygiene of the kind that involves at minimum a daily shower.
Discussing the top three will allow you to get to know a lot more about your partner and rate your suitability. Judge their temperaments, character and make an objective assessment of whether or not you can be with them. Who knows, you might even have the same peeves.
