First, what are the 'sayings' for a perfect town? Two days ago Isabelle told me I had a perfect town and I was able to change the train station and build a flower clock. The 'saying' was the same the next day but today it's different. It still implies that I have a perfect town. I'm mainly hoping something didn't get messed up, especially considering that I didn't change anything and even watered my flowers even though I have 'Beautiful Town'.
Also, do you NEED to water your flowers if you have 'Beautiful Town'? I'm going for the Golden Watering can so I don't want to chance my flowers wilting and dying and I'm watering them anyway. Is this unnecessary or can they still wilt just much less frequently?
