How do you make a best friend on Animal Crossing wild world

It depends on who you want to be friends with really. If you want to be friends with sable just keep talking to her for about a week, and if you want to be friends with Brewster then you have to talk to him for about a week and then he will give you different types of coffee and if you want to be friends with Celeste then all you have to do is when you talk to her you have to click on 'your cute' for about a week and then she will be you friend to. If you want to be friends with your villagers then you have to send them a letter every day, talk to them every day, do something helpful for them every day eg. deliver something and then after a week they will give you their pic and then they will be your friend!!!
