I always say yes when my villagers ask me to come over and visit. I feel like it increases our friendship level. BUT... I am gun shy now when they ask me what I think of their room. I always say I like it a lot because I don't want to be rude (I know I know sheesh). But they ALWAYS act like they are insulted because they can tell I am not being honest. What do you say when they ask? Do they like it better when you give them a "meh" answer?
