A mate is konmari'ing and it reminded me about the mugs thing
When you're a young and you're starting to think about getting your own place you look at the mugs in your parents' cupboards and go "Yeah I like these because I've grown up with them but I don't actually want any of them, I want to go to a shop and buy the mugs that *I* want, in fact that's exactly what I'm going to do"
Sorry, doesn't work like that. Your friends and family will buy you mugs. The person you live with comes with their own mugs that they didn't choose either. You'll have maybe three mugs that either of you actually like, a bunch of Kinda Crappy Mugs, and you'll have four or five more that live at the very very back of the cupboard and you'll stop the dishwasher and rinse a good one by hand rather than drink out of one of the Really Crappy Mugs that you won't throw away.
Most of your mugs will be Kinda Crappy Mugs. Whenever one gets broken you'll say "Oh nO, wHoOpS" in your most sarcastic voice and you'll maybe buy one you actually like to replace it.
"When will I buy My Own Mugs" or even "When will we have Our Own Mugs" is a terrifying question because there aren't good answers; when the old crappy ones break (they won't break because they don't get used), when you throw them away / donate them (but granddad gave me that!), when you suffer some massive tragedy and have to flee the house and all your possessions? Or just... never? How about that huh, how about never?
"Let's ruthlessly discard the crappy mugs and get like a dozen good mugs, all the same good shape but different colours maybe," this is a fantasy. You already have two or three mugs you like, whatcha gonna do with those ones huh?
You don't get to choose your mugs. Sorry. Only gods do that.
