When that happens I usually keep talking to them till they get excited and are like; 'Oh Koo, you have something I want. I have been looking in stores for that thing I just gave you a few minutes ago. How much do you want for it?'I hate when you're trying to give villagers furniture that matches their theme and they try selling it back to you later.
Funny enough after the first two pieces of daisy furniture I sent Nana, she gave me a Daisy Tee. Then I kept talking to her till she wanted the Daisy Tee she just gave me. And from there she started wearing it. Success.
